“Oh Shit, a Pit Bull!” Did Breed Mythology Kill a Dog During a Police Raid?

When I get my time machine out of the shop, I’m going to go back 100 years to tell some amazing things to the dog world. I’m going to tell them that where I come from, Great Danes are gentle companions for children and are one of the most cuddly breeds a family can own. I’m also going to tell them that nanny dogs, as pit bulls were sometimes known, will become so hated and feared that they may be shot on sight. Both predictions will seem so ridiculous that I won’t be believed.

A Drug Raid in Columbia, Missouri

Jonathan and Brittany Whitworth, and their son, P.M., lived in Columbia, Missouri. They owned a pit bull terrier named Nala and a mixed-breed dog named Bruno that may have had boxer, bulldog, and even Corgi in his blood. A SWAT team of at least eight officers executed a search warrant on the Whitworth residence on February 11, 2010. A separate officer with the Columbia Police Department videotaped the raid.

Jonathan Whitworth had a history of drug convictions, and had been sentenced to jail for 15 months in 2003. Informers and neighbors told the police that Whitworth was selling marijuana and was attempting to obtain cocaine. Garbage from the Whitworth residence was confiscated, resulting in paper clips that tested positive for THC, the active ingredient in marijuana. The use of a large SWAT team was justified because Whitworth was said by the police to have a history of physically resisting arrests.

On forcing the door, the SWAT team saw—depending apparently on different accounts of team members—either one or two dogs at the threshold or running towards them. Sergeant Schlude, one of the team members, said, “Oh shit, a pit bull.” Officer Cavener fired a shot at the pit bull 1.09 seconds after entry. Cavener expected the dog to retreat and it did.

The Whitworths, in an amended complaint, said that SWAT officers chased one of the dogs into the kitchen. The pit bull was bleeding and running around the kitchen. The court describes what happened next:

“[Officer] Fox shot the pit bull because he recognized it to be a pit bull and because it was running at his legs and not stopping. Two other officers fired at the pit bull around the same time. One of these officers was Quintana, who stated in his report that he fireed one round at the pit bull because he believed the dog was going to attack him. Officer Quintana had noticed the pit bull with its ears pinned back and postured in an aggressive manner, although he did not testify that it growled, barked, or approached him. Quintana was in close proximity with the pit bull at this point. Officer Horrell observed that right before the officers shot the pit bull, the pit bull had run into a sliding glass door and had gotten up and began to scamper. Horrell later examined the other dog, Bruno, and observed blood on his leg.” (emphasis added)

The court then shifts its attention to Jonathan Whitworth:

“When the first SWAT officer encountered Mr. Whitworth, the officer ordered Mr. Whitworth to get on the ground and put his hands behind his back. Mr. Whitworth got on the ground but put his hands behind is head. Officers told Mr. Whitworth a second time to put his hands behind his back. As Mr. Whitworth went to move his hands behind his back, Officer Hendrick's foot made a single contact with Mr. Whitworth's face and shoulder for the purpose of getting Mr. Whitworth to put his arms behind his back…. The parties dispute whether this contact can correctly be characterized as a kick, but the Court views it as one for purposes of this motion. This kick caused Mr. Whitworth pain, but resulted in no bruising, broken bones, or broken skin, and Mr. Whitworth never received medical attention as a result. Mr. Whitworth was cursing during this altercation, in a manner that Schlude took for aggression.”

Brittany Whitworth went into a bedroom with her son and closed the door. An officer opened the door and ordered her to the front of the house. “Mrs. Whitworth asked if herself and P.M. could move positions to avoid the sight of their deceased dog, and officers brought them outside and into the back of a police car…. Officer Clements entered the police car and whispered to Mrs. Whitworth that one dog was dead and the other had been shot in the leg. Mrs. Whitworth asked for the police car to be moved forward so her and P.M. could not see Nala's body brought out of the house, and Clements complied.” (The ungrammatical use of reflexive pronouns by the court presumably reflects the wording of witnesses.)

Subsequent events of the day primarily described Brittany Whitworth:

“Mrs. Whitworth and P.M. were in the police car for two hours. P.M. was sobbing while in the police car. Mrs. Whitworth asked if her mother-in-law could come pick up P.M., but Clements refused. Police Officers instructed Mrs. Whitworth to leave the car at four different times, and supervised her each time she left. The first time, Detective Rukstad asked Mrs. Whitworth if she had any questions, and she asked Rukstad to tell P.M. that Nala was alive and being taken to be a police dog, with which Rukstad complied. The second time, Mrs. Whitworth went to her garage to get a mop. This was her longest absence from the police car, at seven to ten minutes. The third time, animal control arrived and informed Mrs. Whitworth that they had removed Nala's body and would be taking Bruno for medical attention. The fourth time, Mrs. Whitworth went to the master bedroom to wrap Bruno, who was bleeding in its paw, in a blanket for herself and animal control to carry out of the house.”

Lawsuit Against Columbia Police Officers

Brittany Whitworth filed claims in federal district court under 42 U.S.C. 1983 and Missouri state law. Section 1983 provides for civil redress for deprivation of rights under state law. The court said it had to look at the circumstances “from the viewpoint of a reasonable officer on the scene with knowledge that Mr. Whitworth had a history of resisting arrest,” and held that such an officer could reasonably ensure that “the wounded dog still on the premises did not attack officers in an attempt to defend the Whitworths … [and remove] the Whitworths' dogs—one alive and one deceased—from the Whitworth residence while allowing Mrs. Whitworth to accompany P.M. when possible and while keeping P.M. away from seeing the dogs.”

As to pointing guns at the Whitworths, the court stated:

“The Court agrees that ideally officers would execute search warrants without pointing a gun at women and children not suspected of committing a crime. On the other hand, where officers are aware that a dangerous suspect and two large dogs are on the property, a reasonable officer could, in the heat of the moment, rely on such tactics to prod individuals to move swiftly through a potentially dangerous situation. This is especially true, where shouting and gun-pointing occurred as Mrs. Whitworth and P.M. stepped over Mr. Whitworth—who was lying on the floor—and the danger of resistance by any of the Whitworths was arguably at its highest. In this context, the behavior alleged by the Whitworths did not violate a clearly established constitutional right.”

The court also rejected an unreasonable seizure argument based in part on an analogy to a case in which an officer shot a family dog standing near its owner when responding to a call about a stray dog. Andrews v. City of West Branch, 454 F.3d 914 (8th Cir. 2006) (discussed in Police and Military Dogs). The court, referring to Andrews, stated:

“[T]hat cased involved an officer who—while investigating a call about a stray dog—shot and killed, without provocation, a family dog in an enclosed yard that was standing within feet of its owner…. But the present case, even viewing facts in the light most favorable to the Whitworths, involves a large dog standing its ground in the doorway that a SWAT team is about to enter, or running around a kitchen toward police officers. Even if the Whitworths' dogs were not acting aggressively, the Whitworths have not produced evidence that either of their dogs “presented no danger and [that] non-lethal methods of capture would have been successful.”… Rather, these dogs, simply by standing their ground or running excitedly in the path through which the officers needed to quickly pass to secure the scene, stood to frustrate the officers' important objective of securing and searching the house, and presented a risk of attack to passing officers that was great enough to justify a reasonable officer in incapacitating the dogs. The bullet holes in the Whitworths' property are incidental to officers firing at the Whitworths' dogs, so they require no separate analysis for reasonableness.

“Further, even if the officer Defendants did violate the Whitworths' rights in shooting their dogs, the Whitworths have not shown that this was a clearly established right. The requirement that the right violated be clearly established 'operates to protect officers from the sometimes hazy border between excessive and acceptable force, and to ensure that before they are subjected to suit, officers are on notice their conduct is unlawful.' Samuelson v. City of New Ulm, 455 F.3d 871, 877 (8th Cir.2006) (internal quotes omitted). Federal courts have spoken little about how dogs fit into the analysis of unreasonable seizure under the Fourth Amendment, as evidenced by the scant applicable precedent cited by the parties. Dogs easily qualify as property that can be unreasonably seized by the state, but they also contain a latent threat to human safety that has rarely been weighed under the Fourth Amendment's objective-reasonableness standard. Although some dogs are friendly, others are bred and trained to kill, and dogs of either sort can be unpredictable both in their actions and in the signals they send. This unpredictability can increase if a dog is wounded or its owners are being subdued. The reasonable officer would consider all of this when forced into close proximity with a strange dog by the exigencies of executing a search warrant on a dangerous suspect. The Whitworths cite a Missouri statute outlining the legality of a civilian killing a dog in self-defense, but that would not put a police officer on notice of the constitutional boundaries of subduing a large dog in a quickly changing situation such as this one. Because any constitutional right violated by the officer Defendants in shooting the Whitworths' dog was not clearly established, the officer Defendants are entitled to qualified immunity on this claim.”

The Whitworths also argued intentional infliction of emotional distress in the shooting of the dogs in the presence of their owners. The officers were granted summary judgment on this because the conduct was not intended solely to cause emotional distress to the Whitworths.

Summary judgment was granted to the officers on all counts. Whitworth v. Bolinger, 2011 WL 5838406 (W.D. Mo. 2011).

What Really Happened?

The court's description of the events does not bring us into the Whitworth home as if the testimony could substitute for a hand-held camera. Although the raid was videotaped, I have been unable to find any posting of this video. Some of the description suggests the dogs were trying to escape the gunfire, not run towards it. The stories of the participants naturally support their respective interests, and it is not surprising that the court gave the benefit of the doubt to the police. Nevertheless, the use of the SWAT team and the bin Laden-type raid seems a bit excessive. Jonathan Whitworth, if having enough trouble finding cocaine to sell that the police heard about it, was at most a relatively low-level dealer. Meanwhile, Brittany Whitworth labored mightily to keep the whole incident from permanently scarring her son.

The Whitworths, however, cannot claim complete innocence in the fate of poor Nala. Pit bulls bring out the worst in some people, both those who own them and those who fear them. This is not the fault of the dog, but rather a result of an unfortunate and, given the history of the nanny dog, often inaccurate image in contemporary culture. Engaging in activities that interest the police, if this is what was going on, is likely to put the pit bull in danger, without affording any real protection to a family (unless it is to scare others besides the police).

For a time I made it a habit of suggesting to owners of pit bulls that they might reduce resistance in housing and other disputes by referring to their dogs as American Staffordshire Terriers. Then one day at a local pet store, I heard a man bragging about the fear his pit bull engendered in his guests, which he saw as amusing, and I made my usual, invariably unappreciated, recommendation that there would be less fear if he called the dog a Staffordshire. Clearly irritated, he more mumbled than spoke: “I want them to know it’s a pit bull.”

There is too much of this. The police invading the Whitworths’ home had bought the myth, just as have city councils and other legislative bodies adopting anti-pit bull legislation. The laws are at least as much about the owners as they are about the dogs. We don’t want your kind, and we don’t want the dogs of your kind.

A recent paper reported on survey results of individuals who adopted pit bulls and similar-sized dogs of other breeds from an animal shelter in British Columbia. The study followed 40 pit bulls and 42 dogs of other breeds. Three of the pit bulls and two of the other dogs had to be euthanized at the shelter for aggression. The remaining 77 dogs were given homes. One pit bull and ten dogs of other breeds were returned to the shelter because of “alleged aggression.” Whether this meant the pit bulls were actually less aggressive is not clear. Pit bull adopters were more likely to be under age 30 and may have been more accepting of aggression, or may have even wanted it. Nevertheless, for dogs that were retained for at least two months, owner reports of aggression were similar for pit bulls and non-pit bulls. The authors concluded that their study “provided no evidence of greater aggression or poorer care among adopted pit bulls compared to dogs of other breeds.” MacNeil-Allcock, A., Clarke, N.M., Ledger, R.A., and Fraser, D. (2011). Aggression, Behavior, and Animal Care Among Pit Bulls and Other Dogs Adopted from an Animal Shelter. Animal Welfare, 20, 463-8.

That the owners are responsible for the modern imagery of pit bulls is emphasized in a paper that surveyed 754 college students regarding the breeds they had chosen. The focus was on six breeds: Akitas, Chows, Dobermans, Pit Bulls, Rottweilers, and wolf mixes. The questionnaire the students filled out was intended to assess the type of dog owned, criminal thinking, callousness, personality, alcohol usage, and deviant lifestyle behaviors. The authors of the paper found that “[v]icious dog owners reported significantly higher criminal thinking, entitlement, sentimentality, and superoptimism tendencies. Vicious dog owners were arrested, engaged in physical fights, and used marijuana significantly more than other dog owners.” They concluded that “[c]hoosing to own a vicious dog may be a ‘thin slice’ indicator of more antisocial tendencies.” Schenk, A.M., Ragatz, L.L., and Fremouw, W.J. (online 2011), Vicious Dogs Part 2: Criminal Thinking, Callousness, and Personality Styles of Their Owners. Journal of Forensic Sciences (DOI: 10.1111/j.1556-4029.2011.01961.x).

Conclusion

I occasionally get emails and calls from readers of Service and Therapy Dogs in American Society asking what I consider the ideal breed for therapy dog work. I generally ramble on a bit about my personal predilections, but try to avoid recommending almost any specific breed or mix. However, I usually caution against getting a breed that is going to frighten people. It adds complexity to first interactions. When challenged, I always admit that one of Michael Vick’s pit bulls became a therapy dog. Unfortunately, the reaction of some people to a dog, particularly on first seeing it, will depend on general social attitudes, and pit bulls too often raise the kind of fear expressed by the policeman in the Whitworth case. “Oh shit, a pit bull.”

In this way I have to admit that I am guilty of perpetuating a myth I regard as unfortunate, even offensive. Frankly, I wish that criminals would favor teacup poodles. They would provide as much defense as other breeds—probably more, since their nervousness would better guarantee advance warning of intruders—and they would be much less likely to bring unnecessary gunplay into a police raid.

Thanks for suggestions from Fran Breitkopf and L.E. Papet.

Darwin, Hamilton Smith and the Lost Domestications of South America

Theories of canine domestication are beginning to take into account partial domestications of wolves, such as the 33,000 year old skeleton from a Siberian cave described by Ovodov et al. (2010), and the skull from a cave in Belgium described by Germonpre et al. (2009). Ovodov et al. argue:

“Since dog domestication almost certainly occurred multiple times without direct human selection, we suggest that it must have occasionally failed. That is, the particular set of ecological conditions associated with human settlement and hunting practices that were necessary to initiate the domestication process must have, on some occasions, existed only long enough to produce a few modified wolves (i.e., incipient dogs) with short-lived lineages.”

These researchers suggest that “ecological changes caused by progressive cooling almost certainly caused social and settlement pattern changes severe enough to have disrupted the domestication process and prevented evolution of fully domesticated dogs.” They see their results as supporting a multiple-domestication-events hypothesis for Canis familiaris.

That domestication could occur within the canid family, the Canidae, but outside the genus Canis, was demonstrated by the work of of Belyaev (1979) and his students, particularly Trut (1999), who artificially domesticated silver foxes (Vulpes vulpes), through selective breeding over 30 to 35 generations. The experiment, which continues, left open the question of whether foxes could be domesticated outside of such an experimental environment.

In the 1830s, Charles Hamilton Smith observed canids in South American that were living with indigenous peoples and performing some domesticated functions for them. In one instance, Smith suggested that some apparently different species might actually be tame and wild versions of a single species, raising the possibility that some physical differences could have begun to occur because of the domesticated state. Recent research on pointing gestures with a South American canid closely related to some of the species observed by Smith may also indicate that these lost domestications involved more behavioral change than has previously been recognized.

South American Canids Described by Naturalists in the 19th Century

Charles Hamilton Smith, after discussing the maned aguara (labeled Chrysocyon jubatus by Smith but now generally called Chrysocyon brachyurus) the largest of the South American canids he had encountered, makes some general remarks regarding the animals he will discuss in the following chapters:

“South America, when first discovered by the Spaniards, was possessed of canines absolutely indigenous, some universally wild and others liable to be partially reclaimed; all more nocturnal than the former dogs and less so than the true foxes.”

The first plate is Smith's depiction of the maned aguara. (Double click to enlarge image.) Smith suggests that the name aguara (sometimes transliterated as warrah), attached to so many of these species, may come from the sound they make, “a loud and repeated drawling cry, sounding like a-gou-ā-ā-ā, which is heard to a considerable distance.” (Smith's drawing does not show the ratio of leg length to torso size apparent in pictures of maned wolves, suggesting they may not have been seen often at close range.)

Genetics research, as will be discussed later, has recently indicated that some of the South American canids had a North American origin, but the biological significance of the formation of the isthmus of Panama, the Great American Interchange, was not yet understood. Smith says the maned aguara, the first plate included here from Dogs: Canidae or Genus Canis of Authors, was wild, but records that he had seen various levels of domestication in the other canids:

“Several can be sufficiently tamed to accompany their masters to hunt in the forest, without however being able to undergo much fatigue; for, when they find the sport not to their liking, they return home to await the return of the sportsmen. In domesticity they are excessive thieves, and go to prowl in the forest. There is a particular and characteristic instinct about them to steal and secrete objects that attract their attention, without being excited by any well ascertained motive. All subsist upon the usual food of the wild canines, but with the addition that they eat also fish, crabs, limpets, lizards, toads, serpents, and insects. They are in general silent and often dumb animals; the cry of some is seldom and but faintly heard in the night, and in domestication often learn a kind of barking. None appear to be gregarious, but several are occasionally encountered in families. Although in company with man, the domesticated will eagerly join in the chase of the jaguar, we have never heard that they are in the same state of hostility towards feline as are their congeners in Asia and Africa.”

Smith then states that in the 35 years before completion of his great study of dogs, the natives of South American had shown a distinct preference for European dogs, so that it was by 1839 difficult to find any indigenous dogs associated with them “even in the more remote parts of the interior.”

Hoary Aguara Dog/Fox

The hoary aguara dog was labeled Dusicyon canescens by Smith, but is now generally put in a more fox-like genus and classified as Lycalopex vetulus or Pseudalopex vetulus. He had seen the animal domesticated among the Indians of Brazil, who told him that it remained wild in some areas. Smith described the animal in detail, explaining that he had looked in the mouths of some of the domesticated animals, seeing a black palate as was the edge of the lower lip.

Dalponte (2009) reports the hoary fox is widespread in Brazil and may perhaps be found in Bolivia. It is not threatened with extinction. Courtenay et al. (2006) studied the behavior of the hoary fox, finding that a breeding pair reared a single litter of five offspring per year. The pair associated with no other adults and the offspring dispersed at about ten months of age, the young dogs establishing home ranges adjacent to natal territory. The male adult “acted as chaperone to the foraging offspring, mostly in the absences of the breeding female.” Their diet is mostly made up of termites and dung beetles.

Aguara Dog of the Woods/Surinam Aguara Dog


Smith refers to some Indians having domesticated the aguara dog of the woods, to the left, which he classified as Dusicyon sylvestris, the same classification he places under the heading of the Crabodage, or Surinam Aguara Dog, making a curious reference to “the same species in the wild and domestic states.” He mentions one semi-domesticated specimen obtained from the Indians by the French naturalist, George-Louis Leclerc, Comte de Buffon (1707-1788). Smith gives no details as to the nature of the domestication in his two entries regarding these animals.

Guaraxa Aguara Fox

Smith refers to an “almost insensible degree” of distinction between the Aguara Dogs and the Aguara Foxes, the latter of which are “more completely vulpine, having tails with brushes even larger and longer than those of true foxes.” He says that they “can be domesticated, and it is believed will form cross breeds with Dusicyon and Canis familiaris.” The Guaraxa Aguara Fox, which he labels Cerdocyon guaraxa, “barks, lives on terms without restrain when brought up in the house,” and can be used in hunting “though with but indifferent docility.”

“It is to this species in particular we allude when remarking upon the singular propensity manifested by them to steal and secrete particular objects: bridles and pocket-handkerchiefs have been carried off in this manner, and subsequently found in bushes at some distance.” Smith saw them often chained because of the tendency to eat chickens.

Crabodago Aguara Fox

Smith labels the crab-eating fox Cerdocyon Azarae, but acknowledges the classification, Canis Azarae, given by Prince Maximilian of Wied. The consensus classification at present appears to be Cerdocyon thous azarae. He notes that this type was “represented in the Zoology of the Beagle.” Part of the description of the Guaraxa Aguara Fox is placed under the description of this animal, and may apply to its partially domesticated state as well.

Slater et al. (2009) find that the crab-eating fox and the hoary fox (Lycalopex vetulus) are separated by perhaps a million years, making interbreeding quite possible. They also estimate, however, that the South American canids are separated from the Canis genus by over 10 million years. All of the South American species except the maned wolf, the bush dog, and the Falkland Islands wolf are depicted by this team as having common ancestry about 5 million years ago.

Schwartz (1997) notes a report on interbreeding of a South American canid with domestic dogs, though the species of the canid is not certain:

“The Makusi of Guiana had domestic dogs but would also adopt a wild canid called a maikong. This ‘wild dog’ probably was a crab-eating or pampas fox. A tame maikong was the most treasured possession of the Makusi. It was fed cooked flesh, fish, and ripe plantains. The Makusi said they liked to breed the maikong with their domestic dogs because the offspring make the best hunting dog. In 1925 a female pampas fox reportedly gave birth to two litters fathered by a fox terrier hybrid, but such an event must have been extremely rare. South American canids that have been tested have a different karyotype (the diploid number of chromosomes) from dogs and other members of the genus Canis, and the offspring of such crosses would usually be sterile.”

Wang and Tedford (2008) state that the raccoon dog (Nyctereutes) of eastern Asia appears to be closely related to the crab-eating fox.

The Mystery of the Falkland Islands Wolf

Darwin encountered the Falkland Islands wolf on the Beagle in 1833 and 1834:

“The only quadruped native to the island is a large wolf-like fox (Canis antarcticus), which is common to both East and West Falkland. I have no doubt it is a peculiar species, and confined to this archipelago; because many sealers, Gauchos, and Indians, who have visited these islands, all maintain that no such animal is found in any part of South America…. As far as I am aware, there is no other instance in any part of the world, of so small a mass of broken land, distant from a continent, possessing so large an aboriginal quadruped peculiar to itself.”

He noted the boldness of the animal, which would enter a tent and pull meat from beneath the head of a sleeping seaman. The Gauchos had taken to killing them “by holding out a piece of meat in one hand, and in the other a knife ready to stick them.” He noted the rapid decline in their numbers, and suspected, correctly, that they would soon be extinct. They were extinct by about 1876. Decades after visiting the island Darwin still remembered the innocence of the animal (1875, vol. 1):

“It deserves notice, as bearing on other animals as on the dog, that at an extremely ancient period, when man first entered any country, the animals living there would have felt no instinctive or inherited fear of him, and would consequently have been tamed far more easily than at present. For instance, when the Falkland Islands were first visited by man, the large wolf-like dog (Canis antarcticus) fearlessly came to meet Byron’s sailors, who, mistaking this ignorant curiosity for ferocity, ran into the water to avoid them.”

Smith called the animal the Falkland Islands Aguara Dog, and thought it similar to a coyote (Lysiscus cagottis). He related earlier accounts that “the Falkland Island wolf had originally been set on shore there by the Spaniards, with a view to prevent foreign nations finding fresh provisions at the anchorages: the information stated further, that the wolves had nearly destroyed an indigenous fox, and taken possession of its burrows.” Although Smith questioned that the Spaniards were responsible for the presence of the animals, he believed that an indigenous fox could be found on the western island. He had mistaken young for a separate species. Smith cited Louis-Antoine, Comte de Bourganville, who settled Port St. Louis in 1763, as having seen the animal burrowing along the sea and feeding on birds, emitting a feeble bark.

Juliet Clutton-Brock (1977) believed that human agency would have to explain the presence of the unique wolf on the Falklands:

“The shortest distance between the mainland and the Falkland Islands is too great (approximately 480 kilometers) to imagine the successful dispersal of this animal to the islands unless taken there by man. Nor is it likely that a single mammalian species, and a large carnivore at that, survived on the islands throughout the Pleistocene when periods of periglacial conditions prevailed.”

Clutton-Brock thus found the Falkland Islands Wolf something of an Atlantic analogue to the Australian dingo and she noted some of the same physical characteristics that suggested prior domestication: “white markings on the pelage, a wide muzzle with large somewhat compacted teeth in the premolar region, and expanded frontal sinuses.”

Slater et al., analyzing nuclear and mitochondrial DNA derived from one of the few remaining pelts, concluded that the closest remaining relative was the South American maned wolf (Chrysocyon brachurus, discussed above).

“Molecular dating analyses suggest that the Falklands wolf and several extant South American canid lineages likely evolved in North America, prior to the Great American Interchange. The Falklands wolf was the sole representative of a distinct South American canid lineage that survived the end-Pleistocene extinctions on an island refuge.”

This team of researchers noted the explanations given for the presence of the unique species on the Falklands, including that of Clutton-Brock and the idea that the animals may have been carried from the mainland by ice or logs. The team concluded that the animal “may have reached the islands by rafting or dispersing over glacial ice during the late Pleistocene and was probably able to survive into the recent past by subsisting on a rich diet of penguins, geese and pinnipeds.”

Human agency in the transportation of wolves to the Falklands has become unlikely, but the paleontological record is sparse and it is not impossible that further finds will make this theory viable again.

Flux in the Taxonomy of South American Canids

In 1931, Cabrera described the confusion in classifying the often similar canids of South America, noting that some naturalists would put most of them in the Canis genus, while others provided for much more separation. Slater et al. suggest that at least “six exclusively South American canid lineages, including the Falklands wolf, originated prior to the formation of a Panamanian land bridge,” and that the “South American canids probably evolved from the fossil taxon Eucyon, which was widespread in North America during the late Miocene [c. 7- 5 million years before present]. The ultimate extinction of South American canid lineages in North America may have resulted from resource competition with Canis, which immigrated to the New World during the late Pliocene [5.3-2.6 million years before present].”

The significance of this research can perhaps be visualized by superimposing some of the findings of Slater et al. on the relevant section of the taxonomic chart of Wang and Tedford. Wang and Tedford's connections are depicted as continuous lines, with Roman type on the side, while Slater et al.'s findings use dotted lines and italics on the side. The separation of the maned wolf and the Falklands wolf in terms of time is not significantly altered by Slater et al., though the connection between the crab-eating fox and the hoary fox is much more recent. Wang and Tedford indicate in one chart (Figure 7.1, p. 140) a connection between the Eucyon line and South American canids, but it appears that they do not see the connection as direct as described by Slater et al. In any case, changes to the current taxonomic arrangement are likely to result from the work of Professor Robert Wayne's group at UCLA and Professor Eduardo Eizirik's group in Brazil. Additional complexity is also added with Prevosti's 2010 phylogenetic study of extinct South American canids.

Pampas Foxes Follow Human Pointing Gestures

Three researchers from the Instituto de Investigaciones Médicas in Buenos Aires looked at communication between humans and the Pampas fox (Lycalopex gymnocercus), similar to earlier pointing gesture research on dogs and wolves. The Pampas fox is, at least for the moment, in the same genus as the hoary fox. Seven foxes, which had been living at an experiment station for at least five years, learned that if they gazed at a human face, they received a food reward. The foxes looked longer at a human's face when a reward was offered, but less so when it was not. Once food was provided again, the animals looked longer again.

Four of the animals that had participated in the first phase were then tested for their ability to find hidden food after receiving human cues. Two opaque containers were used for the choice test. Each had a piece of liver under a false bottom to control for odor cues. Proximal and distal pointing gestures were employed--i.e., gestures in which the arm closest to the correct container pointed, and gestures where the arm crossed the body to point to the correct container. In the former situation, all four foxes performed above chance, while in the latter, three out of four did so.

The researchers concluded that "foxes, an undomesticated species with low socialization to humans, were able to follow human gestures to find hidden food." Since some of the South American canids, at the time that Smith observed them, were living in semi-domesticated states, it seems likely that they would have learned to follow human gestures for a number of purposes.

Dogs Near Coastal Argentina by 1000 AD

Smith noted the preference of Indians for European dogs as a reason for the decline in domestication of the indigenous species, yet recent archeology has found dog burials near the coast of Argentina by about 1000 AD. Prates et al. (2010) note that “the presence of prehispanic dogs in South America has always been associated with complex societies (mainly in Peru and Ecuador) and not with egalitarian hunter-gatherers.” Finds in Peru and Ecuador mostly date from 3,500 years before the present onwards. Yet, this team notes that “some reporters’ and tavelers’ stories from the sixteenth and seventeenth centuries indicate that Patagonian hunter-gatherers already had dogs at the time of the first Hispanic-Indian contacts.”

The team described findings in the north of Patagonia about 100 miles from the Atlantic. The culture used stone tools and dogs were found in an area of continuous occupation. A second burial, about 170 miles away in the Pampas, was in a cemetery, where a “dog was buried intentionally with a 2- or 3-year-old boy, his right arm extended near the dog’s head, in a posture remarkably similar to the famous Natufian burial from Israel. Analysis of the skeletons at these sites indicates they were “somewhat larger than the common Mesoamerican dog,” closer to a Cocker spaniel in size “and similar to a spitz-like breed or a chow chow.”

Conclusions

Except for one curious reference in Hamilton Smith, it appears unlikely that any of the fox-like canids that achieved semi-domestication had separated from wild populations sufficiently to be morphologically or genetically distinguished. The fact that the team working with Pampas foxes found that some animals were too frightened of humans to be tested may indicate that the semi-domesticated canids had to be raised with humans to be put on leashes and handled by humans, and may indicate that this had been going on for generations by the time Smith arrived in South America. Unfortunately, the cessation of any domestication process with the arrival of dogs from either prehispanic or European cultures makes investigation difficult, and absent some exceptional archeology, probably impossible.

Nevertheless, even from Smith one gets the sense of something of a continuum of the fox-like wolves, or wolf-like foxes, that involved a number of species similar in appearance and which might, depending on the environment, be confused with each other. There were undoubtedly subspecies occupying different but sometimes overlapping habitats. Smith's speculations about interbreeding of similar species are likely to have had some basis in fact.

One also gets the sense that before the increase in European dogs, a wide range of indigenous cultures formed relationships involving various degrees of domestication with these animals. They accompanied the hunters, lived in their huts and may have eaten vermin. Their generally limited vocalization would have likely made them of little use as guards and their timid and curious natures may have made them useless in combat with other tribes. (As I noted in a prior blog, if any of the South American canids, including the dogs of the Incas, had had any defensive value, the conquistadors would have had a much harder time.) Still, some connections were formed, but then easily broken when the more devoted, more domesticated dogs arrived.

Do the human-canid relationships described by Smith say anything relevant to the domestication of dogs from wolves? Some of the South American canids do not seem to have had a strong fright response to humans that had to be overcome. Nor is there any evidence that the South American indigenous cultures saw the canids as competitors for the same food. Although mentioned in connection with hunts, the animals do not seem to have been nearly as helpful as hunting dogs, probably because large game was of no interest to them. Humans may have helped them expand their own ranges, however, and may have taken them to places where birds and crabs could be found, along with the large game that interested the humans. When living with humans, they could learn to bark, and may then have had some defensive value, though this seems to have been relatively minimal. The fact that the canids would be tethered to keep them from eating chickens suggests that despite certain disadvantages, they were still considered of value.

The canids had a place in the cultures closer to that of the terrier than the large hunting dogs that are often seen as fitting the needs of Eurasian hunter-gatherer societies. If these South American domestications are to be regarded as failed, as dead ends, it might be suggested that absent the introduction of Spanish and perhaps prehispanic dogs into the cultures involved, something like the artificial domestication of Belyaev’s foxes might have been possible. These domestications of the wolf-fox-like canids may also suggest that different cultures could have different domestication events, that no single cultural prototype explains how domestication can occur.

U.S. Can Learn from Australian Debate over Success Rates of Detection Dogs

A debate now going on in Australia deserves the attention of those in the U.S. involved in using, and particularly those responsible for funding, detection dogs. While American courts sometimes consider the relevance of a dog’s accuracy rate in prosecutions, there is far less discussion on this side of the Pacific as to whether the overall success rate of drug and other detection dogs justifies their costs. There is also far too little recognition that poorly designed and implemented protocols, procedures, and practices, including inadequate training and continuing education, allow or even encourage false alerts, cueing, violations of individual rights, lawsuits, misuse and mistreatment of dogs, and other consequences that add to the bottom line of canine programs and make them harder to justify to governments and taxpayers.

Success Rates of Drug and Explosives Dogs in New South Wales

The issue was touched off when David Shoebridge, a member of the New South Wales Upper House of Parliament, asked the Minister for Police and Emergency Services the following questions (in italics) and received the answers (in Roman type).

How many complaints about police sniffer dogs were received by the NSW Police Force in the following years:
(a) 2007?
10
(b) 2008? 8
(c) 2009? 9
(d) 2010? 11
(e) 2011 to date? 5

(2) How much money has been paid out by or on behalf of the NSW Police Force or the state of New South Wales in response to legal proceedings relating to police sniffer dogs in the following years:
(a) 2007?
$35,000 (Australian dollars)
(b) 2008? $85,000 (plus costs as yet unresolved)
(c) 2009? None
(d) 2010? None
(e) 2011 to date? None to date

(3) What expenses have been incurred by or on behalf of the NSW Police Force or the state of New South Wales defending legal proceedings relating to police sniffer dogs in the following years:
(a) 2007?
$19,827.79
(b) 2008? $164,086.78
(c) 2009? None
(d) 2010? None
(e) 2011 to date? $6,671.52

(4) What records are kept of each search by a police sniffer dog? Records are kept in relation to all requests that are received. Each individual search is then recorded on the COPS system in the case of drug detection dogs, and via spreadsheet in the case of firearm and explosive dog searches.

(5) How many searches were conducted using police sniffer dogs in the following years?
(a) 2007?
Drug dogs: 7,603; firearm/explosive dogs: 1,160
(b) 2008? Drug dogs: 10,562; firearm/explosive dogs: 1,128
(c) 2009? Drug dogs: 17,321; firearm/explosive dogs: 791
(d) 2010? Drug dogs: 15,779; firearm/explosive dogs: 551
(e) 2011 to date (April 30)? Drug dogs: 6,965; firearm/explosive dogs: 108

(6) How many searches involving a police sniffer dog found any illicit substances in the following years? Only drugs were considered in the answers.
(a) 2007?
2,435
(b) 2008? 3,748
(c) 2009? 5,109
(d) 2010? 5,087
(e) 2011 to date (April 30)? 2,103

(7) How many searches involving a police sniffer dog found indictable quantities of illicit substances in the following years: 2007-2011 to date? The police replied that this information could not be determined from police records.

(8) How many searches involving a police sniffer dog found weapons in the following years:
(a) 2007?
11
(b) 2008? 7
(c) 2009? 8
(d) 2010? 5
(e) 2011 to date? 1

Thus, there were 58,230 searches using detection dogs in the nearly four and a half-year period, resulting in 13,892 drug finds, a success rate of 23.9%. In the same period, there were 3,738 searches for using firearm/explosive dogs, resulting in 32 weapons being found (though no bombs are mentioned), a success rate of less than 0.01%. Combining both types of detection dogs for which figures were sought produces a success rate of 22.5%.

The Sydney Morning Herald, in an article posted online on December 12, updated the figures for 2011, indicating that through September 14 of 2011, 102 searches produced drugs 2,854 times, a success rate of only 20%.

According to the Sydney Morning Herald, Shoebridge said that “no test which has an 80% error rate could be considered a reasonable basis on which to conduct an intrusive public search of a citizen going about their daily business.” He said that with such a high error rate, targeting young people and Aborigines, the program should be halted. “If this was happening in the car parks of merchant banks, there would be outrage.”

The police response was that often found in the U.S.: if drugs were not found, it means that the person was using them recently, or had been in their presence, meaning that the alert was valid, just unproductive. The New South Wales Police Minister, Mike Gallacher, said the government fully supported the use of dogs because the police had found them effective.

New South Wales Ombudsman’s Report

There has been a tradition in Australia of reviewing the cost effectiveness of detection dogs. Most dogs are used in New South Wales and Queensland, the most populous part of the country (see the CIA map), and the Australian Customs Service has a Detector Dog Program. New South Wales has long had general police dogs, some of which were trained in drug detection, but did not begin to use specialized drug detection dogs until the 2000 Olympic Games in Sydney. Most detection dogs in Australia are Labradors. Dogs are generally trained with food rewards and taught to give a passive alert.

In a report published by the New South Wales Ombudsman in 2006, Review of the Police Powers (Drug Detection Dogs) Act 2001, the Ombudsman concluded that “despite the best efforts of police officers, the use of drug detection dogs has proven to be an ineffective tool for detecting drug dealers. Overwhelmingly, the use of drug detection dogs has led to public searches of individuals in which no drugs were found, or to the detection of (mostly young) adults in possession of very small amounts of cannabis for personal use.” (See also, New South Wales Council for Civil Liberties, analysis of the Ombudsman’s Paper.)

The high cost of the program, and its marginal results in targeting drug suppliers, led the Ombudsman to question “whether the drug Dogs Act should be retained at all.” The Act was in fact repealed, though this did not mean the end of detection dogs, only the end of certain expanded police powers regarding their usage. The Drug Dogs Act had conferred on police the power to use drug detection dogs without a warrant in certain public places such as pubs, on public transport routes, and sporting and entertainment venues. The Act also required the Ombudsman to review the success of the use of dogs under the Act.

Use of Detection Dogs in New South Wales

The Ombudsman’s Report describes police procedures:

“Police distinguish the screening of people by the drug detection dog from the searching of people conducted by police. The distinction is important because the Drug Dogs Act does not require police to have a reasonable suspicion about a person in order to use the drug detection dog for screening. To search a person, police must have a reasonable suspicion that a person is in possession or control of a prohibited drug.”

The use of one dog was described in a drug dog case, DPP [Director of Public Prosecutions] v. Darby, NSWSC 1157 (2002) as follows:

“The evidence established that Rocky [the drug detection dog] had been trained to detect the scent of cannabis. When he did so his training caused him to put his nose in the air, flair his nostrils, and sniff rapidly. He would then follow the scent to its source. When he reached the source of the scent, he was trained to put his nose on such source and sit down beside it. If the scent emanated from a person’s pocket, Rocky was trained to put his nose on the pocket and then sit down beside the person.” (emphasis added)

In this particular case, Rocky placed his nose on the suspect’s pocket, resulting in a find of 2.89 grams of methamphetamine and 1.9 grams of marijuana. Darby was charged with two counts of possession of prohibited drugs.

Vapor Wake Analogy?

Following scent to source bears a significant resemblance to Auburn’s trademarked Vapor Wake Detection Program, where dogs are “trained to alert if they detect any explosives in the air and follow the explosive to its source.” Government Accountability Office, Technology Assessment: Explosives Detection Technologies to Protect Passenger Rail, GAO-10-898 (July 2010). Although the GAO accepts Vapor Wake Canines as “an emerging use of EDCs [explosives detection canines] that may be applicable to the passenger rail environment,” and refers to “generally positive results,” there is no indication that the agency has requested or received any statistical evidence of the sort available in Australia as to the success rates of the dogs. This would not be an unreasonable request, given that the Metropolitan Atlanta Rapid Transit Authority, according to the GAO, has been using such dogs since 2006 (the Ombudsman was gathering such data from the beginning of the sniffer dog program).

That searches using such scent-to-source trained dogs could be conducted on the street is indicated in a description of a 2003 incident from notes used in preparing the Ombudsman’s Report:

“Dog indicates a man seated with a group of other people at a table. The handler taps him on the shoulder and explains about the dog and cautions him. The man says that he had a smoke about three hours ago. He is given an explanation about the scent of the cannabis still being on him. Police officer says, “Just come out with me, mate. We’ll get it sorted.” The man says he is ‘freaked’.”

About 84% of incidents in the period reviewed by the Ombudsman (from 2002 to 2004) involved marijuana, though ecstasy, methamphetamine, cocaine, and other drugs were also found. All but one of the incidents involved less than 300 grams, for which no legal proceeding followed. Australian police can issue warnings and cautions in non-prosecutable situations.

The Ombudsman concluded that in only 26% of the time where a dog indicated were drugs subsequently found. This accuracy rate was not consistent with statements made by the dog handlers, such as, “my dog never lies,” though handlers were willing to accept that other handlers make mistakes, but often insisted on the accuracy of their own dogs:

“We’re not going to turn around and say, ‘oh, the dogs sniffed them, OK, well we’ll stop them’. The dog’s just sniffing, and as the trained handlers, we know that. Perhaps the other police we work with don’t know, but we’ll just go, ‘nup that’s wrong’. So it’s a load of crap. The dogs don’t indicate on food or cats or dogs. They might sniff them. They might pay them a little more attention, but that person’s not being stopped or searched or anything else just because they’ve been sniffed.”

Should There Be a Minimum Rate of Success to Justify a Program’s Existence?

As to the question of what level of accuracy is acceptable, the Ombudsman’s Report stated:

“It is not possible to point to a rate of finding drugs which is universally thought of as acceptable in terms of accuracy and effectiveness. While some might say that a rate of 1 in 4 is commendable, others will be concerned that three quarters of those searched are not found to be committing any offence. Others point to the number of admissions of drug use that accompany the searches where no drugs have been found to indicate that the dogs are highly accurate, detecting miniscule residual traces. Still others might comment that it is unduly narrow to focus on statistical rates when other benefits of the use of drug detection dogs and high visibility police patrols are no less important but are less quantifiable. For example, it has been argued that the drug detection dogs contribute to reducing fear of crime in the community, deterring and disrupting drug networks and reducing other forms of crime such as assaults and thefts.”

It is to be noted that finding “miniscule residual traces” might be acceptable in some environments, such as schools, but the Drug Dogs Act did not include schools in the definition of a “public place” where a warrantless search could be conducted. The Ombudsman continued:

“What is clear is that in practice, drug detection dogs provide the sole basis for the police reasonable suspicion to search a person. The dog can be viewed as a tool used to engage this suspicion. One might expect a higher standard of accuracy and reliability when using a tool, such as metal detectors or breathalysers, than of a police officer acting in the course of his or her duties without the assistance of any tools.”

The Ombudsman then reviewed several U.S. cases discussing accuracy rates, for which see Police and Military Dogs, Chapter 8, “Accuracy Rates.” One professor questioned whether a 27% accuracy rate was any better than chance, noting that about 35.5% of 20 to 29 year-olds and 27.7% of 14 to 19 year-olds in Australia were using drugs according to one survey. In other words, randomly searching individuals in these age groups would probably produce results similar to those from using a dog, at much less cost.

The Report acknowledged that one sniffer dog used by the police had a 56% success rate, though another had only a 7% success rate. The table reproduced here compares the rates of 17 dogs over a two year period from February 22, 2002, to February 21, 2004. All supervisors of canine units should keep such tables of dogs in their units, and all governmental authorities should demand such recordkeeping, along with cost figures.

Deterrent Effect Doubted

The Ombudsman’s Report rejected any deterrent effect in the use of police dogs:

“We were not able to find, nor were NSW Police able to provide, any evidence that the use of drug detection dogs disrupted low-level street dealing in a sustained manner. Similarly, we were not able to identify any evidence that the use of drug detection dogs has had a deterrent effect on drug users, or led to a reduction in drug-related crime. Nor were we able to measure any appreciable increase in perceptions of public safety as a result of high visibility policing operations utilising drug detection dogs. Further, there was no evidence that police obtained intelligence information during drug detection dog operations that led to further investigation of drug supply.”

At another place in the Report, however, the Ombudsman acknowledges that “it is not possible to determine the deterrent effect of drug detection dogs or whether they contributed to the general downward trend in drug offenses.”

The Australian experience is clearly different from that in the U.S., where it has often been possible to obtain significant information from street-level users regarding their suppliers.

Significance of the Australian Debate

Trolling sports and entertainment venues with drug dogs, given that most individuals caught are going to be given warnings even if caught with something, seems a waste of police time at the expense of the public. The failure to target environments where drug suppliers may be found is a good argument for altering police practice, but not necessarily for eliminating drug detection dogs.

In prior blogs we have been concerned that dogs should not become a failsafe method of justifying a search when nothing else pans out. Pressure to produce an alert is a primary source of cueing, cueing that will often result in a false positive. As we have argued, the results of cueing are insidious throughout the criminal justice system, even if American courts have been slow to recognize the issue and prosecution witnesses reluctant to acknowledge it. False alerts, whether from cueing, poor training, or otherwise, reduce the cost effectiveness of canine units. Handlers and police administrators should understand that ignoring cost effectiveness may ultimately result in costs being cut altogether.

Even if residual odor can continue as a mantra to excuse a low field accuracy rate in criminal prosecutions, the number of times drugs are not found by a department’s canine unit after alerts has to be accounted for an expense without result. Australia has been more focused on the cost benefit of canine units than have politicians and administrators in the U.S. This is likely to change as more governments at all levels become strapped for cash and are forced to consider how crime can be fought most efficiently, and cheaply.

We believe that the dogs will win in the end, that there are thousands of good law enforcement dog handlers in the United States, but we also believe that recordkeeping could substantially improve, and should be made more comprehensive and uniform across the U.S., on a model similar to that used by the New South Wales Ombudsman. Such results should regularly be reviewed by police administrators and governments, and published for the benefit of governments, courts, and the public.

Seizure of Drugs in Plain View Was Legal, but Search Following Dog’s Alert Should Have Waited for Warrant (Not That It Mattered)

Officer Michael Sweeney saw Shayna Kline make a U-turn against a red light on Martinsville Road in Bernards Township, New Jersey. Kline later disputed that she had turned on a red light, saying that she had waited for the light to turn green. Sweeney pulled the vehicle over and approached the passenger side of the vehicle. Officer Kazinsky, also on patrol, pulled up in a separate patrol car. Kline argued at trial that her car was targeted because it had out-of-state plates and that Sweeney must have already called for backup even before stopping her because Kazinsky arrived so quickly.

Sweeney, using a flashlight, saw what he believed to be marijuana and tobacco on the floorboards of Kline’s vehicle. Marijuana often looks like dirt from a distance of several feet so there was likely a significant amount or portions of joints were visible.

Sweeney asked for the driver’s license, registration, and insurance card, but Kline could only supply a “photocopy like” identification card. The passenger only had a non-government identification card from Maryland. Kline was asked to exit the car. When asked for her Social Security number, she could not remember it. Although she said she had been dating her passenger, Vladimir Reynoso, for three years, she could not remember his last name. She did not make eye contact and appeared nervous. Questioned separately, Reynoso said he was not dating Kline.

After learning Kline’s license had been revoked, Sweeney separately secured defendant and Reynoso in different patrol cars. It’s not clear why Kline was not immediately arrested, allowing for a search incident to the arrest or an inventory search. In any case, Sweeney entered the vehicle and found pieces of marijuana, tobacco, and cotton balls. He detected a strong odor of marijuana from the trunk area, he later testified, though he did not put this information in the warrant application. Sweeney then sought consent to search the vehicle but Sweeney refused. Cotton balls are used in the drug culture, for cleaning spoons and needles, to add moisture to marijuana, etc., but it was not explained why they were in the car.

Patrolman Dockery, by this time the senior officer present, requested a “canine dog,” a redundant term that apparently was the court’s or a witness’s way of describing a narcotics detection dog. Since drugs had already been found, providing probable cause for further action, it is not clear why a dog was needed at this point unless it was to test the dog, or because there was some feeling on the part of the officers that they might not have been able to convince a court that drugs had, in fact, been in plain view.

The dog arrived and, according to the opinion, alerted to the presence of marijuana. Most likely the dog was trained to alert to more than marijuana, and arguably could have alerted to another odor, but marijuana was the only drug found. Kline again refused to consent to a search of the vehicle and was told that it would be seized and a search warrant sought. Kline and Reynoso were arrested and brought to Bernards Township Police headquarters. Officers went to the judge’s residence and she granted their warrant application. Drugs were subsequently found in the trunk.

Trial

At trial, the court accepted the police version of events and concluded that “the presence of marijuana … the conflicting stories from … defendant and Mr. Reynoso, and defendant’s nervous and evasive behavior in response to question,” meant that “Officer Sweeney had probable cause to search the passenger compartment of defendant’s vehicle.” The court also found that holding the defendants until the emergent judge made herself available at 7 a.m. was reasonable. The seizure of marijuana from the floorboards of the car was found to be justified under the plain-view exception to the warrant requirement.

The Supreme Court of New Jersey, in a case decided in 1983, had stated that there were three requirements to the plain view exception:

1. The police must be lawfully in the viewing area.
2. The officer has to discover the evidence “inadvertently,” meaning that he did not know in advance where evidence was located nor intend beforehand to seize it.
3. It must be “immediately apparent” to the police that the items in plain view ere evidence of a crime, contraband, or otherwise subject to seizure.

New Jersey v. Bruzzese, 94 N.J. 210, 463 A. 2d 320 (1983). The appellate court in the current case, New Jersey v. Kline, No. A-6126-09T2, 2011 WL 557382 (Ct. App. 2011), determined that these requirements had been met, in that Sweeney (1) had articulable suspicion to make the stop and be within the viewing area, (2) did not know he would see marijuana when he got to the car, and (3) it was readily apparent that there was marijuana on the floor of the car.

The defendant testified that she had been in the gas station for 28 to 30 minutes before she tried to drive away. What was going during this 28 minutes, a time period that does not seem to have been controverted by the prosecution? It was certainly enough time for the police to choreograph the sequence of their actions after Kline began to drive away and should have been of considerable interest to defense counsel for arguing that the plain-view exception might not have been satisfied.

The trial court then concluded that exigent circumstances and probable cause had justified the search following the dog's alert.

Appeal

The appellate court concluded that the seizure of the marijuana from the floorboards was justified under the plain view exception to the warrant requirement. Nevertheless, this court stated:

“We disagree, however, with the trial judge's ultimate conclusion that based upon all of these circumstances, the subsequent warrantless search of the vehicle's interior and under the hood was justified. While there were sufficient facts, measured objectively, from which Officer Sweeney had probable cause to believe that evidence of a crime may be found in the car, the circumstances at that point were not exigent. Defendant's vehicle was not stopped in a high crime area…. Defendant and Reynoso were being detained by at least two, possibly four, Bernard's Township police officers when Officer Sweeney commenced his search of the vehicle's interior. The testimony also revealed that there was a prosecutor and a judge on emergent duty…. Moreover, although the judge inexplicably required the officers to wait until seven a.m. to obtain the search warrant, this delay was not unreasonable, particularly since defendants were in custody based upon the seizure of narcotics found in plain view. Therefore, making an application for a search warrant was not impractical…. Under these circumstances, beyond entering defendant's vehicle to retrieve the suspected marijuana observed in plain view on the floorboards, the search of the interior and under the hood of defendant's vehicle was not justified under exigent circumstances.

“Nonetheless, no drugs or other contraband were seized as a result of this illegal intrusion. Moreover, the search warrant subsequently issued was valid. The facts upon which the warrant was issued did not include Officer Sweeney's detection of a strong odor of raw marijuana upon entering the vehicle. Rather, the judge was advised of his observation of suspected marijuana during the course of a motor vehicle stop for a traffic violation, that defendant did not have a driver's license, and that the canine dog alerted to the presence of drugs from the exterior of the vehicle before entering the vehicle and alerting to drugs from the interior. Thus, the illegal search of the vehicle's interior by Officer Sweeney and the canine dog was sufficiently attenuated from an otherwise valid seizure of drugs based upon the plain view exception to the warrant requirement and a validly-issued search warrant. Hence, there is no basis to reverse the order denying defendant's motion to suppress the evidence seized from the trunk.” (emphasis added)

The appellate court affirmed the trial court’s decision.

Open Questions

Since holding the defendants until a judge could be asked to issue a warrant was not unreasonable, and calling for the dog upon Kline’s refusal to allow a search was justified, it would appear that the dog’s sniff did not unreasonably prolong the stop or otherwise violate Kline’s rights. Why the dog’s alert did not provide sufficient probable cause for a warrantless search of additional parts of the vehicle and a full search of the interior was explained as coming after a point where there were no exigent circumstances, the car was not in a high-crime area, and a warrant could be obtained. Also, “the illegal search of the vehicle’s interior by Officer Sweeney and the canine dog was sufficiently attenuated from an otherwise valid seizure of drugs based upon the plain view exception to the warrant requirement and a validly-issued search warrant.”

The attenuation reference is in need of more specificity since the court’s position could be interpreted as meaning that the search subsequent to the sniff could not fit within any extension of Caballes. (See U.S. v. Marquez, 2005 WL 455858 (3d Cir. 2005), citing Illinois v. Caballes, 543 U.S. 405 (2006), holding that an alert at the trunk of a vehicle established probable cause to search it and arrest the driver.) The reason that Caballes and its Third Circuit and New Jersey progeny could not apply should have received some attention.

Attenuation is applied in probable cause situations where “the connection between the lawless conduct of the police and the discovery of the challenged evidence has ‘become so attenuated as to dissipate the taint.’” Wong Sun v. U.S., 371 U.S. 471 (1963), quoting Nardone v. U.S., 308 U.S. 338 (1939). Thus, sufficient attenuation between an illegal search or seizure and later evidence does not require application of the exclusionary rule. Segura v. U.S., 468 U.S. 796 (1984). In Brown v. Illinois, 422 U.S. 590 (1975), the Supreme Court elaborated that the “notion of the ‘dissipation of the taint’ attempts to mark the point at which the detrimental consequences of illegal police action become so attenuated that the deterrent effect of the exclusionary rule no longer justifies its cost.” The illegal search, as to which the subsequent discovery of evidence must be attenuated for that subsequent evidence to be admitted, is the root of the poisonous tree as to which the subsequent evidence is fruit. See U.S. v. Dupree, 617 F.3d 724 (3d Cir. 2010). Here, the illegal canine search followed the initial plain-view seizure and presumably the question is whether this subsequent activity, having been declared illegal, would taint the warrant. The fact that no drugs or contraband were found in this second search was stated by the appellate court before mentioning that the warrant was valid. It is not clear whether drugs, if they had been found in this tainted search, would have been admissible though an inevitable discovery argument could have been made. Attenuation, in any case, would not help the prosecution here.

If the illegality of the search following the dog's alert is simply a determination that after the initial probable cause, the initial seizure, and the arrests, a warrant could have been obtained and further investigative procedures delayed until it was obtained, this raises additional questions. For instance, if the dog had alerted and plain view of the marijuana had not occurred until the search based on the dog’s alert began, could the dog-supported search have been continued? More specifically stated: if the hood or trunk had been raised because of an alert and drugs found, and the occupants arrested before an officer saw marijuana in plain view inside the car—say after the occupants had left it and shut the doors behind them, would searching the interior of the car have then required a warrant? It would seem so if the order of events can determine what supports a search, and conceivably the extent of a search in a vehicle that can have drugs in a number of places. Or should such a hypothetical reversal of the order of events be distinguished because the subsequent plain view of an officer involves no separate effort, unlike bringing a drug dog to a car? Answering such questions would provide additional understanding regarding the potential application of Caballes to real-world decision-making on the part of police.

It is to be noted that although the plain view exception might restrict a search or seizure to the area where illegal items were in plain view, this has not been held by some courts considering the extent of a vehicle search based on a sniff. See U.S. v. Carter, 300 F.3d 415 (4th Cir. 2002) (alert at driver’s door justified search of trunk); Ohio v. Bolding, 1999 WL 334494 (Ct. App. 1999) (alert gives probable cause to search entire vehicle). For further discussion see “Specificity of Alert” in Police and Military Dogs, Chapter 8.

Conclusion

The lesson appears to be that the more reasons for probable cause the better because some may drop away through a court’s analysis of the circumstances. Watching a car for nearly half an hour in a gas station is a long time and suggests that the discovery of anything in plain sight might not have been particularly “inadvertent.” Perhaps this potential weakness in the police procedure explains why calling the dog was deemed necessary. Police are well advised to obtain a warrant as efficiently as possible once an arrest has been made, at least where evidence is in no danger of disappearing and a judge can be made available.

An Overly Friendly Dog Pushes Over a Guest: Is Suing Owners of Goosers a New Profit Center in Personal Injury Law?

My dog sometimes gets rambunctious and runs between the legs of guests. We can generally control this, and try to warn people to be on their guard on entering our house. Being a lawyer, I suppose I have always had in the back of my mind the question of whether I might be liable if somebody falls down and breaks a hip.

A recent decision by an appellate court in New Jersey provides some perspective on this issue for those of us who have overly friendly dogs. The fact that the dog’s owner was not liable in this particular case should not lead people who own “goosers,” “bumpers,” and “running through you” dogs to believe that they can never be liable when such demonstrations of interest or affection get out of hand.

A Longstanding Friendship

Rochelle Puzzutiello and Gail Wurster became close friends in 1995. They spoke on the phone daily and frequently spent nights at each other’s homes. Puzzutiello moved to Florida in 2004, but they continued their phone conversations nearly every day. Puzzutiello returned to New Jersey for holidays and kept her apartment in Audubon.

Wurster was diagnosed with cancer in early 2009 and Puzzutiello made plans to return to New Jersey as soon as Wurster was out of surgery. On March 23, 2009, Puzzutiello’s brother, Joseph Ezzi, drove her to Wurster’s home. On entering the house through the back door, Wurster’s dogs were at her feet and neither seemed excitable or unruly to Puzzutiello, and they remained calm while she unpacked.

The visit progressed without incident until Puzzutiello tripped over the younger dog, named Lucy, who weighed about forty pounds and was described by Puzzutiello as “lovable” and “very gentle.” The fall fractured Puzzutiello’s ankle. The incident was described by Wurster to an investigator as follows:

“The three of us [plaintiff, defendant and Ezzi] were in the living room area of my house, talking.... The dogs were overly excited I guess[ ] to see the guests in the house. And me, on my return home from the hospital[.] I was sitting in the chair and the two dogs were near [plaintiff] who was standing near the television, actually she was walking away from me. The smaller dog [Lucy] followed her and moved between her legs causing her to trip. She couldn't regain her balance and fell into the wall.... I knew she was injured seriously.... I want to say again that I felt terrible about this accident. I feel that it was the action of my smaller dog, Lucy when she placed herself between [plaintiff's] legs that caused her to trip.”

Trial Court Grants Summary Judgment

The trial court granted summary judgment to the defendant, stating:

“These are dogs. These are dogs that are walking around in their owner's home, their owner's back from the hospital, sitting—recovering from surgery. This is a family friend who's been in the company of the dogs many, many times. Whether the theory of liability here is that ... defendant should have known that the dogs were especially excitable and had a duty to protect the plaintiff by putting the dogs in some other room or controlling them or otherwise preventing them from causing this injury to the plaintiff[,][t]his is not a dog bite case. This is not a dog jumping on somebody. This is not a dog walking in an unruly fashion. This is a dog in a house with its owner, with its friend, the plaintiff, who as the plaintiff is walking moves between [plaintiff's] legs and causes her to trip....

“The court finds as a matter of law that under those factual circumstances, the defendant had no duty of care to place the dogs somewhere other than in the living room. The plaintiff came to meet with [defendant] and while the court ... feels badly that the plaintiff was injured, the court can find no duty of care on the part of the owner who was recovering from abdominal surgery, who was in her house, who was with her dogs. The—sadly, the plaintiff tripped. She tripped over a dog that was walking around in a room that the dog lived in.”

Appellate Court Reviews the Facts and Law

Puzzutiello appealed, arguing there was a genuine issue of material fact and that summary judgment should not have been granted. The New Jersey appellate court noted that when “there exists a single, unavoidable resolution of the alleged disputed issue of fact, that issue [is] insufficient to constitute a ‘genuine’ issue of material fact…” under New Jersey evidentiary rules (quoting Brill v. Guardian Life Insurance Company of America, 142 N.J. 520, 666 A.2d 146 (1995)).

The appellate court, in a decision written by Judge Linda Baxter, provided its own summary of the facts, stating:

“[W]e conclude that Lucy moved between plaintiff's feet as plaintiff was returning to the sofa. However, there is no evidence in the record warranting a conclusion that Lucy, the dog that tripped plaintiff, was in any way unruly, excitable or out of control on the day in question. Plaintiff herself described Lucy as a “gentle” and “lovable” dog, and plaintiff acknowledged that she had never had any concerns about Lucy during any of the numerous occasions she had visited defendant. Although plaintiff stated that defendant's other dog Gabby was a “jumper,” the record is devoid of any evidence remotely suggesting that Lucy, who was the cause of plaintiff's injury, had ever acted in a manner that endangered plaintiff or anyone else. Nor was there any indication that on the day in question, Lucy had been doing anything other than sitting at defendant's feet prior to the moment when the dog apparently stood from that position and began to follow plaintiff back to her seat on the couch. We reject plaintiff's claim that there were disputed issues of fact that required the judge to deny defendant's motion.”

The court noted that Puzzutiello was not claiming that Wurster should have put the dogs in another room, only that Wurster should have warned her the dogs were unruly or excitable. The court noted that while liability might have applied for a dog bite, there was no bite here. The court noted that the question was whether landowner liability applied, but a “host has a duty to warn a social guest of a dangerous condition on the property only when the host has actual knowledge of a dangerous condition of which the guest is unaware.” Here, Puzzutiello had been to Wurster’s home many times and “was familiar with defendant’s dogs, their demeanor, and the fact that they could move, and were frequently ‘in the say’ and ‘wanted to be the center of attention.’”

The court elaborated:

“[P]laintiff here knew a dog was present and that the dog might move from where it was sitting. Because plaintiff was aware of the dog's presence in the home, and in the specific room where plaintiff was situated, defendant had no duty to warn her that the dog might move, as this was a readily observable condition of which plaintiff had knowledge. Moreover, in light of plaintiff's concession that Lucy had been acting 'fine' during plaintiff's entire visit, there was nothing about the dog's behavior that could have triggered any duty on the part of defendant to warn plaintiff that she should be especially careful about the dog. We therefore conclude that under the facts presented, there was no duty to warn plaintiff, who was a social guest, that the dog Lucy posed any danger to plaintiff.”

The appellate court concluded that the trial court had not erred in granting summary judgment, and affirmed.

One would like to know if the two remained friends, or if the real defendant was an insurance company, but nothing outside of the court record seems, at least so far, to have reached the media.

Different Facts Might Produce Different Results

Those of us with friendly pets should recognize that there might be circumstances where summary judgment would not be granted. If you know your dog has a tendency to push people over, and the guest does not know this, you have a duty to give a warning. Although the situation is not identical to a bite, liability might still attach. Don’t assume that an injury will always be overlooked, either by a litigious guest or a court.

Although the facts of this case involved a plaintiff visiting the defendant in her house, one could easily imagine an overly rambunctious dog at a dog park causing an injury to another user. A google search for "over friendly dog" + "personal injury" suggests that a number of lawyers specializing in dog bites now devote a portion of their practices to representing plaintiffs injured by overly friendly dogs.

If you have such a dog, it’s probably worth asking your insurance provider about the extent of your coverage for pet incidents. Bites are usually covered in general homeowners’ policies, but your insurer may not have thought about the fact that a friendly dog can sometimes be as injurious as an aggressive dog.
