School District Resists Autism Service Dog, but Benefits Outweigh Control Problems

K.D., an autistic child, attended an Illinois elementary school. In May 2009, the boy received a Labrador retriever, Chewey, from Autism Service Dogs of America (ASDA). The court kept the child’s identity and the family’s name confidential, but news reports have identified them. The Villa Grove School District soon sent K.D.’s parents a letter saying that Chewey could not accompany K.D. to school. In July 2009, K.D.’s parents filed suit, seeking a court order permitting K.D. to bring Chewey to the school. The school district filed a motion to dismiss the case because (1) the parents had not exhausted administrative remedies before beginning their suit, and (2) Chewey was not a service animal under the Illinois School Code, which specifies:

"Service animals such as guide dogs, signal dogs or any other animal individually trained to perform tasks for the benefit of a student with a disability shall be permitted to accompany that student at all school functions, whether in or outside the classroom." 105 ILCS 5/14-6.02

The trial court denied the school district’s motion to dismiss, and Chewey went with K.D. to school during the 2009-2010 school year.

The parents then sought a court order to require the school district to:

1. Train at least one primary staff member and one backup staff member in the commands needed for Chewey to accompany K.D. to all school functions.
2. Designate one primary staff member to hold Chewey’s leash while K.D. is also tethered to Chewey during transition periods throughout the school day.
3. Designate one primary staff member to release K.D. from his tether while he uses the restroom facilities and during periods with heavy physical activity, such as gym classes.
4. Allow Chewey access to water and to relieve himself during the school day.

The trial court denied this relief, finding the request exceeded the scope of the School Code.

At a hearing, Kati Witko, an ASDA program training director, who trained dogs to assist autistic children, described Chewey’s training. Dogs receive approximately 16 months of training, beginning when they are six to eight months old. Dogs in training are taken to schools to learn to remain calm around children with loud behavior. Dogs are taught to remain at a down-stay position with a child, and not to move from that position unless commanded by a handler.

"Witko stated Chewey is not currently commanded by K.D. because K.D. does not function at a level where he could provide Chewey with a sense of leadership or control. Rather, he is specifically trained not to respond to K.D.'s commands, and thus someone else must command him. Although Chewey knows over 30 commands, a handler needs to know only 5 to manage Chewey in a school environment. Chewey's main handler is K.D.'s mother, Nichelle."

After Chewey had been trained in Oregon, he was assigned to the family in Illinois. Witko went to Illinois to teach Chewey how to apply his training to K.D. This should have involved working in the school as well as the home, but since the school district was not at the time allowing Chewey into the school, Witko had to return in August 2009. At that time she spoke with K.D.’s speech teacher, his one-on-one aide, the head of special education at the school, and some “fill-in” aides. Witko left her contact information with school officials but no one from the school contacted her and her follow-up calls were never returned.

Chewey was taught to “stand his ground” when tethered to K.D. to prevent him from running into traffic or other dangerous situations. Tethering is intended to give the child some sense of independence and to reassure family members and school staff that the child will not be able to run. Chewey was also taught a command to apply deep pressure with his head or a paw to K.D., which Witko described as something children with autism “seek and need.”

Nichelle D. the boy’s mother, testified that K.D.’s autism frequently caused him to run away and into dangerous situations, even leaving the house at night while the rest of the family was asleep. K.D. only slept two to three hours a night. After obtaining Chewey, K.D. became upset for shorter periods of time, completed his homework, and began to sleep six to eight hours a night. Chewey barks if K.D. leaves his bed. He began to go to school calmly and happily, without tantrums.

K.D.’s one-on-one aide, Aimee Reardon, helped K.D. “transition” from place to place and do his homework. She testified that the dog did nothing without a command, but said that commands often had to be repeated two to three times. She said Chewey would bark at other dogs near the playground and try to go to dogs. Sometimes he barks in school and sniffs other students. Removing his gentle leader was sometimes difficult. Sometimes K.D. would try to give Chewey commands that differed from those Reardon was giving the dog, which seemed to confuse Chewey.

Kathy Burgess, a full-time aide for the school district, tethered and untethered K.D. and Chewey in the classroom and lunchroom, and also testified to Chewey’s barking at other dogs and sometimes having to be restrained from trying to get to them. She also said that commands had to be repeated. She said she had not notified Witko about Chewey’s barking because it was not a consistent problem.

Beth Wiessing, a speech-language pathologist, met with K.D. four days a week during the 2009-2010 school year. She expressed concern that Chewey “increasingly” stood up when K.D. stood up, despite not being commanded to do so. The dog once ignored a command to stop following K.D. down a hallway when K.D. was untethered. She also complained of having to repeat commands to the dog. She described K.D. as throwing more tantrums after being paired with the dog, as increasingly repeating vocalizations of other persons (a condition called echolalia), and said that the child’s use of spontaneous language had decreased.

The trial court ruled that Chewey was a service animal because he had been individually trained, the child had a disability, and the dog had been trained to perform tasks for the benefit of the child. The court said that to be a service animal the law did not mean that the dog had to perform tasks flawlessly.

The school district appealed, continuing to insist that Chewey was not a service animal, an argument that was a loser on the facts. The appellate court affirmed the trial court in concluding that Chewey was a service animal, as well as denying the argument regarding exhaustion of administrative remedies. This court agreed with the trial court that even if Chewey’s behavior sometimes varied from his training, the Illinois School Code “does not specify service animals must behave perfectly at all times.” Nor does the statute require that a child’s educational and behavioral performance be evaluated before an animal qualifies as a service animal. In testifying, some of the staff seemed to make too much of minor problems and I had to wonder if they were all on board with the school district’s position and the litigation strategy that came from it.

The school district argued that the dog did not “accompany” K.D., as allowed by the School Code quoted above, because K.D. was not Chewey’s handler. The court found this argument sophistic. Given that the trial court had rejected the parent’s motion to require that numerous staff be trained to handle Chewey while K.D. was at school, neither the trial nor the appellate court required the school to provide a handler. This is somewhat analogous to the situation where a facility is required to admit a service animal, but not to care for it when the handler is unable to take care of the dog. For instance, a hospital may be required to admit a service dog accompanying someone who is getting an MRI, but not required to take care of the dog during the MRI. The patient has to bring an alternative handler. The teachers and aides at a special school must adapt to each child, however, making the situation different from a hospital providing an MRI where no staff member would be responsible for a patient in the same way. If a child uses a prosthetic device, for instance, a school would have to train staff to help the child with the device and the same could be said to be true of a service dog. (See 105 ILCS 4/14-1.08, referring to Special equipment for use in the classroom, required by the child because of his disability….”; see also 105 ILCS 4/14-8.02, referring to “supports” for children with autism spectrum disorders.) Since an aide and other staff performed handler functions during the 2009-2010 school year, it must be hoped that the school district will not now argue that an aide would have to be hired by the parents to assume this role.

The school arguably could have based an argument on the dog’s effect on other children in the school, though I think that this would fail because the school would have to reasonably accommodate conflicting interests. The Illinois Code provides that the service animal “be permitted to accompany that student at all school functions, whether in or outside the classroom.” So even if other children are allergic to dogs, satisfying the statute would require that children be separated into different classes to avoid the problem. At least one family has expressed concern about the safety of their child at the Villa Grove Elementary School. Service dogs are trained not to be aggressive and such concerns would probably have been resolved had the school worked with the ASDA trainer. If counseling did not resolve a child’s fears, again the statute would require the school to find an accommodation for both children.

Schools, service dog organizations, and the parents of the child receiving the service dog should reach a formal agreement as to their responsibilities for a service dog before a dog is placed in a school setting. Patty Dobbs Gross, Executive Director of North Star Foundation in Storrs, Connecticut, says that getting a school to buy into the advantages of a dog working with a child at school is extremely important to help everyone concerned in traveling up the necessary learning curves. Such important topics as bullying from normally developing students can be addressed through the introduction of a service dog if the dog is used as an educational tool. According to Patty, who runs tolerance programs with her service dogs in training at schools, there is no better way to teach tolerance than through the eyes of a puppy being trained to help a child with a disability.

From a staff training perspective, it was unfortunate that the elementary school involved in this case did not work with the trainer from ASDA. The dog could, for instance, have been taught to play in the schoolyard with the children, returning balls with his nose. This would likely focus the attention of the dog on the child (or children) rather than on other dogs within sight of the schoolyard, as well as help to integrate the child with autism socially with his peers. Such training glitches as Chewey sniffing children and being slow to respond to commands from adults would also have been addressed in a timely manner. As Rick Manley of the Phoenix Field and Obedience Club taught me long ago, repeating commands is a way of training the dog to respond to a command only after it has been repeated several times.

The accommodation requirements of some of the newer service dog types may present more difficult questions than merely whether a dog is a service animal. Autism service dogs are required to deal with complex situations, and a child that is abusive to a dog may not be a good candidate for a service animal, but this is one case where the advantages of the dog to the child were very clear. The resistance that formed somewhere in the administrative hierarchy of the school district was most unfortunate.

K.D. v. Villa Grove Community Unit School District No. 32 Board of Education, 936 N.E.2d 690 (Ill.App. 4 Dist. August 24, 2010). For a discussion of autism service dogs and some of the relevant research, see Service and Therapy Dogs in American Society (pp. 79-83).

Email Comment. I received an email from someone who has been following the case who points out that the dog is apparently conflicted when K.D. gives Chewey commands. She points out that this indicates that the dog is willing to respond to the boy's commands and that some bond has formed. When autism service dogs do not bond with a child, the dog tends to ignore the child's efforts to control it, and may even shy away from the child.

Huang Hua, Joan Hinton, and China, 1984

Two people that I met in China died recently. Last week it was Huang Hua, once Vice Prime Minister of China, who entertained my father and the members of his family traveling with him in a dining hall in the Forbidden City in Beijing. More on that later. The other was Joan Hinton, whom I met on a collective farm in rural China. My father led a group of American agriculturalists around China for 30 days in 1984. Instead of just visiting the cities, we spent much of our time in the country so that the agricultural scientists could talk with the people running the large farming operations. Joan Hinton and her husband were on a farm that had a large dairy operation that Hinton’s husband, Erwin Engst, had helped build. The couple had raised their children in China and Mrs. Hinton told me that her son, who had returned to the United States for college, had an accent that for some reason was mistaken as German, not Chinese.

The Hintons wore Mao jackets, which was curious since this was twelve years after Nixon’s visit and eight years after Mao’s death. Most government officials by then were wearing well-tailored Italian suits. My father said that Engst and others had built a very good dairy operation from scratch, and he was impressed. He did not know anything about Hinton and it was only after her obituary appeared in the New York Times in June of this year that I learned of her connection to the Manhattan project and the suspicion that she may have been a spy. The couple struck me as good natured old lefties of the sort that one could still find in the coffee shops along Telegraph Avenue in Berkeley in the 60s talking about visiting Trotsky in Mexico before his assassination by Stalin's agents.

Huang Hua was a very different story and to tell what I know about him requires that I explain why my father was in China in the first place, By the time I went with him in 1984 my father and mother had been to China five times. They had first gone in 1972. When Nixon returned from China my father got a call from Earl Butz, then Secretary of Agriculture, whom my father had known for more than a decade. As my father told it, Butz’s first words were, “You’re going to China.” My father had no connection with China and asked why. “They asked for you,” was Butz’s reply. “But why me?” my father asked. “I don’t know.” In time my father did find out. In the 1950s, he had written up some research he found in a journal published in Hong Kong. The paper had been roughly translated into English and my father saw the results as significant. He wrote about this in several places, but never knew that it had come out of Red China. He told me he had assumed it had been done in Taiwan or Hong Kong. My father’s attention gave the paper international recognition at a time when Chinese research was often ignored by western scientific publications. The Chinese never forgot and when Butz asked if they had a preference about who could lead the first exchange of livestock producers, they asked for my father.

So in late 1972 my father went to China. He met several officials and spoke at the University of Beijing, but he spent most of his time talking to the leaders of collective farms. Because he went to parts of China where no American had been for a generation, his return flight was routed through Washington where he was debriefed by someone from the Pentagon. According to my father, he made a lousy spy because, in his words, "I couldn't tell a missile silo from a grain silo." (Actually I'm quite sure he could, but it was probably his way of saying that the debriefing made him uncomfortable. He thought that agriculture should be outside of politics, if not above it.)

My father kept going back. Several times he asked me to come with him, but the time required either conflicted with school (I was in law school until 1974) or work. Finally I went in 1984. The dinner in the dining hall in the Forbidden City with Huang Hua and his wife was perhaps the most unique event I have ever attended. My father had been dealing with the Vice Prime Minister for years and the two had become friends, but the rest of us were in awe of the man who had met with Henry Kissinger to bring down the barriers that had separated China from the United States since 1949. After the dinner was over and we were being taken back to our hotel, my wife turned to me and said, “Two little nebbishes from New York have just had dinner with one of the most powerful men in the world in one of the most unusual places in the world.” Indeed. At about 3 a.m. the entire group of about 20 were wakened and driven to see Mao, whose body, preserved in an inert atmosphere, had not been visible to the public for some months while his mausoleum was being repaired. There were large plastic sheets hanging around the walls of the room to prevent the public from looking in. The time was selected so that no one would know that an American group had been allowed to see Mao when others were being denied the privilege. It was a favor to my father from Huang Hua.

I wish that I could say that I had seen paintings of Pekingese dogs on the walls of the imperial palace, but I didn’t. The only dogs I remember from that trip were the several varieties of dogs that the shepherds in Inner Mongolia kept for their herds. They are hardy animals. With the cold winds and long winters of Mongolia, they have to be. My mother took some pictures of these dogs for possible inclusion in a revision of The Complete Book of Dogs, which my father never got around to. My efforts to find the pictures my mother took of the Mongolian dogs have so far been unsuccessful. The picture here is from stock photography.

Are Terrorist Threats Changing Constitutional Parameters of Police Behavior? Considering an Incident at the Minneapolis/St. Paul Airport

An opinion of a federal magistrate shows that narcotics detection dogs at airport screening must be deployed before a seizure of a passenger’s carry-on luggage has become unlawful under the Fourth Amendment. The facts of the case also show something about how TSA and airport police hand off cases to each other during screening procedures. Conducting a dog sniff during an initial search of the luggage at an inspection table would have been legal under the magistrate's analysis, but detaining the luggage and the passenger in a separate screening room without probable cause or reasonable suspicion meant that the subsequent sniff by the drug dog was fruit of the poisonous tree and had to be thrown out. Would the result have been the same had a bomb dog been used instead of a drug dog?

A Passenger with $90,000 in Cash. Johnny Chan was selected by an airline for heightened TSA screening on his boarding pass. Cosgrove was working at Security Checkpoint 5 at the Minneapolis/St. Paul International Airport on July 20, 2007. (The diagram from the airport's website shows the configuration of security checkpoints.) Chan’s belongings went through the X-ray machine and Chan walked through the metal detector. The X-ray operator told Cosgrove that there were three large opaque items in Chan’s bag. Chan was led to a screening table where he was frisked by Cosgrove in what the TSA calls a bulk item pat-down. Cosgrove searched Chan’s bag and discovered a black plastic garbage bag with three bundles of cash. Cosgrove asked Chan what the money was for and Chan said it was to buy copy equipment in Chicago. Cosgove called over his supervisor, Finch, because significant amounts of cash were considered unusual circumstances. So far, it appears there was nothing illegal about the procedures.

Finch told Cosgrove to return to his regular duties. Finch asked Chan what he was doing in Minneapolis. Chan said he had been looking at colleges with his daughter but according Finch was unable to name a single college they had visited. Another witness said that Chan had mentioned Concordia College and the court concluded that Chan’s answers had been adequate. Chan appeared nervous and was sweating during the questioning but the court apparently determined that this was not unusual under the circumstances.

Finch told Kohanek, the TSA supervisor on duty, about Chan, indicating he was not satisfied with Chan’s responses. Kohanek walked to Chan with two airport policemen. It was unclear who had called the airport police. Even thought the screening process was completed, Chan was escorted by the two officers into a private screening room, about 20 feet from the screening table. Chan was not told that he was free to leave. It was unclear if Chan’s boarding pass and ID had been returned to him. The magistrate found that the detention became illegal at this point. The purpose of the stop had been completed and the airport police “had neither probable cause nor even a reasonable articulable suspicion that the luggage contained contraband or evidence of a crime.” Chan had not been told he was free to leave and no reasonable person in his situation would have thought so. Arguably, however, Chan’s nervousness in the face of questioning and his inadequate answers, had the court accepted Finch’s version of events, could have justified further inquiry. Nervousness has been found by some courts to provide reasonable suspicion for additional detention during traffic stops and in other situations, allowing for a canine sniff.

Husby of the Airport Police Department spoke to Chan in the private security room until a K9 officer arrived with a dog. Chan was not asked if he would consent to having his luggage subjected to a dog sniff. Husby testified that it was normal procedure to have a narcotics dog smell large amounts of currency. The dog alerted to the cash and Chan was removed from the security checkpoint to the police operations center. (The dog’s alert was most likely to methyl benzoate, a substance in street cocaine. The canine evidence was not challenged by Chan and the reliability of the dog was not discussed in the opinion. Nor was it determined how long Chan had held the cash, which would be important in calculating whether the methyl benzoate got onto the cash while it was in Chan’s possession.) Chan was then told he was free to go but that his cash was being seized. By this time Chan had missed his flight to Chicago. Also about this time, Husby and other officers learned that Chan had an outstanding arrest warrant but the officers decided not to execute the warrant. The warrant was a felony arrest warrant for financial fraud.

The government contended that Chan voluntarily consented to the investigation into the facts surrounding the cash, but the court held that “any reasonable traveler in Mr. Chan’s circumstances would have perceived that he was not free to leave from the moment he and his luggage were seized by TSA Officer Cosgrove, until he was released after the APD refused to return his money to him after the dog sniff.” The magistrate concluded that the $90,000 seized from Chan was the fruit of an unlawful seizure of his luggage and an unlawful detention and the money had to be suppressed. Specifically, the luggage was unlawfully seized when the airport police took possession of it with neither probable cause nor reasonable suspicion. The magistrate stated:

"At the moment of seizure, the police knew only that Mr. Chan had $90,000 in U.S. Currency, that he made no effort to conceal, and that he was transporting to Chicago. Mr. Chan knew the amount of money and answered the officer's questions about what he intended to do with it. Until the dog alerted to the money, the police had found no drug related evidence on Chan's person, or in his luggage. While the police later learned that Mr. Chan had a criminal history, they did not know that until after the dog sniff…. Neither the TSA, nor the police officers were able to articulate a basis for believing the money carried by Mr. Chan was drug related. Their respective descriptions of why they continued to investigate the money rise no higher than the level of a 'hunch', which is insufficient to warrant an investigatory seizure of Mr. Chan's luggage."

The magistrate said that even assuming there was reasonable suspicion allowing continued detention, the length of the detention here exceeded Constitutional bounds of a permissible search and seizure. Had the police executed the outstanding warrant as soon as they knew of it, this might have provided a lawful basis to seize the cash incident to the arrest. U.S. v. $90,000 in United States Currency, 2009 WL 6327469 (D.Minn. 2009).

A Slightly Different Scenario. Let me change a few facts and discuss whether the result should be the same. Instead of financial fraud, suppose that the officials discover that the warrant was issued by a foreign country and may have involved providing financial support for terrorists. Also suppose that instead of a drug dog, the dog was a bomb dog and alerted to the cash. Some explosives contain highly volatile chemicals that could adhere to currency. (Admittedly, terrorists could more easily separate those handling explosives from those handling cash than is generally the case with cocaine on currency, where the currency is often received from cocaine users. I could get around such an objection by just stating that the dog alerted to a suitcase, rather than cash in it.)

It is obvious that the full body scans that are now so riling the air travel public would not be tolerated were their objective to find drugs. The threats of explosives on passengers or in luggage or cargo are so horrifying as to change the boundaries of police behavior, and I suspect, judicial perspectives. Chief Justice Warren, more than forty years ago in Terry v. Ohio, 392 U.S. 1, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968), put the “threat of physical harm” to the officer involved and potentially others in the balance for determining whether the officer’s actions in a stop were reasonable. If the federal district court had found that the passenger’s nervousness justified detention for the sniff, then the seizure might have been approved. Would the court have favored the version of events argued by the government if the situation had involved possible terrorism? This would not result in a change of the letter of the law, but rather in a court’s tendencies in dealing with the facts of a case. Yet change it would be.

At Berkeley I took a seminar from the great scholar of ancient law, Professor David Daube. In one class Daube asked us why so many of the great works of Roman law dated not from the height of the Roman Empire, but rather from well into its decline. Was there something about legal reasoning that allowed it to flourish as a civilization neared its end? I don’t remember that Professor Daube really answered his question. It was more to make us think but this was decades before terrorism became part of daily life and fear. Now it strikes me that as a society becomes more paranoid when the enemy gets closer, the interpretation of rights is going to change in a reflexive effort to deal with the threat, particularly if the threat is invisible. It may be cloaked as a return to an ancient austerity, from a time when a different enemy was at the gates. Although I cannot say exactly how it will happen, it is obvious to me that cases involving terrorism are becoming a mechanism for restricting freedoms we Americans hold so dear.

For security reasons, some cases are deflected from public exposure in various ways. A case like my hypothetical, for instance, might have been dealt with by putting a homing device in the cash to follow the passenger’s subsequent movements, rather than an arrest. There would have been no case. Unfortunately, we live in interesting times.

Navy Oversight of Canine Operations Needs To Improve: Hazings in Bahrain

The Log Cabin Republicans sued the United States and the Secretary of Defense, Robert Gates, alleging that the “don’t ask, don’t tell” policy violated the rights of its members under the First and Fifth Amendments. Federal Judge Virginia A. Phillips of the Central District of California held that 10 U.S.C. 654, stating Congressional policy concerning homosexuality in the armed forces, was unconstitutional.

One of the stories brought before the court was that of Joseph Rocha, who enlisted in the Navy in 2004 when he was 18. His family had a multi-generational history of military service and Rocha wanted to become an officer in the Marine Corps despite not having been admitted to the Naval Academy. He set his sights on entering the Officer Training School as an enlisted man. After basic training, Rocha was promoted to seaman apprentice and volunteered for a military mission to Bahrain. There he sought out the base’s canine handler position because he wanted to become an explosive-device handler. He tested for a kennel-support assignment, but his contact with other handlers was limited to a few on the night shift.

In time, Rocha passed oral and written examinations to qualify for an assignment in kennel support, where he cleaned, fed, medicated, and exercised explosives detection dogs. Meanwhile, Rocha also earned martial arts, combat, and swimming qualifications. Judge Phillips describes what happened next:

When the eighteen-year-old Rocha declined to participate in the unit's practice of visiting prostitutes, he was taunted, asked if he was a “faggot,” and told to prove his heterosexuality by consorting with prostitutes…. [The canine unit commander, Chief Petty Officer] Toussaint freely referred to him as “gay” to the others in the unit, and others in the unit referred to him in a similar fashion…. When Rocha refused to answer the questions from [the Petty Officer] and others in the unit about his sexuality, “it became a frenzy,” in his words, and his superiors in the canine unit would gather around him, simulate sexual positions, and ask if the U.S. Marine Corps soldiers performed various sexual acts on him…. [The commander] ordered all of the other men in the unit to beat Rocha on the latter's nineteenth birthday.

On one occasion that Rocha testified was especially dehumanizing, [the commander] brought a dozen dogs to the Department of Defense Dependent School for a bomb threat training exercise. For the “training exercise” he instructed Rocha to simulate performing oral sex on another enlisted man … while [the commander] called out commands about how Rocha should make the scenario appear more “queer.” …On another occasion, [the commander] had Rocha leashed like a dog, paraded around the grounds in front of other soldiers, tied to a chair, force-fed dog food, and left in a dog kennel covered with feces.

Rocha did not discuss his sexual orientation with his commanding officer, who was obviously not tolerant, but in any case he wanted to comply with the don’t ask, don’t tell policy. Eventually, Rocha returned to the United States and was assigned to the Lackland Air Force Base for Military Working Dog Training School. After completing this training, he returned to Bahrain and encountered the same atmosphere. The new commander was as prejudiced as the last, telling Rocha that he was everything the commander hated, “liberal, Catholic, and gay.” The new commander continued haunting and harassing Rocha and put an image of two men engaging in homosexual activity on Rocha’s computer. Despite the egregious mistreatment, Rocha at first declined to complain about a superior even when he was being investigated on another matter.

Rocha received numerous commendations and was awarded the Navy and Marine Corps Achievement Medal and in 2006 received the sole nomination from his Congressman for entrance into the U.S. Naval Academy. At that time, reflecting on the long-term commitment a Navy career would entail, Rocha informed the Navy of his sexual orientation. Several Officers tried to dissuade him from coming out, telling him he was being considered for various honors and leadership positions, including a battalion leadership. Rocha persisted and received an honorable discharge.

While it has not been my intention to enter into non-canine policy debates, I do think losing this man was a serious loss for the Navy. What concerns me here is that this case refers to practices that suggest that some military working dog commands overseas may not be run very well and that oversight may be deficient or lacking several steps up the chain of command. Why was there a kennel covered with feces? Why was a person dogs were expected to obey put into positions that the dogs might see as justifying a lack of obedience on their part? Why did a training exercise involve simulated sexual positions? What were the dogs being taught to do? Sniff terrorists at gay bars in Bahrain?

Maturity is crucial in working with dogs, particularly with explosives detection dogs expected to have a high level of reliability. Putting the command of a military dog unit in a dangerous location in the hands of individuals with the maturity of a bunch of drunken frat boys should be of grave concern to the military and taxpayers alike. The Navy has said the incident is under review. Rocha has written about his experience. Toussaint was forced to retire.

Using a Bite-and-Hold Trained Dog for Search and Rescue Leads to Lawsuit

The police receive a call that a boy is lost, drunk, and wearing very little on a cold night. An officer arrives with a dog trained in tracking and suspect apprehension. The dog apprehends with a bite and hold. The department has a tracking dog that is used in search and rescue, but it is not available because of a recent injury. Should the police use the bite-and-hold dog? The issue recently faced a canine officer in Maryland. I'll refrain from editorializing while the matter remains in active litigation.

Judge J. Harvie Wilkinson of the Fourth Circuit Court of Appeals tells the story better than I could:

Around 7:00 p.m. on the night of March 17, 2006, Oscar Melgar, then thirteen years old, learned about a birthday party from his friend, Brian Bentacur. Oscar received permission from his mother to go to the party with Brian, and Brian's mother agreed to take the boys. The party was in Gaithersburg, Maryland, approximately thirty minutes from Oscar's home in Rockville, Maryland.

Brian's mother picked up Oscar around 8:15 p.m., and the boys arrived at the party around 8:45 p.m. Approximately thirty minutes after the boys arrived, an older youth, who was about seventeen years old, started pouring mixed alcoholic beverages of rum and cola. The beverages were served in eight-ounce cups. Oscar knew he was being served alcohol, although he had never had a drink before. Within ten minutes of his first drink, Oscar consumed two additional eight-ounce rum and colas. He began to feel the effects of the alcohol in the middle of his third drink but still finished it.

Brian also was drinking, and one of the girls at the party complained that he was becoming “too touchy.” Oscar was told to take Brian outside to “walk it off.”

The outside temperature was in the upper thirties or lower forties, and even Oscar later admitted that it was cold. Oscar was wearing jeans and had a green warm-up jacket over his shirt. Brian wore jeans but only had on a long sleeved shirt.

The boys started walking, intending to circle the block, but they were not familiar with the neighborhood and got lost. As they walked, Oscar could feel the effects of the alcohol growing stronger, and Oscar testified that Brian also appeared to be growing increasingly intoxicated.

The two boys eventually sat down on a lawn. Oscar had a phone but wanted to sober up before calling Brian's mother to pick them up. After sitting on the lawn for a few minutes, Oscar saw a man walking a dog approaching. Oscar, who admits he was drunk and not thinking straight by this point, got up and walked away. He crossed the street, headed down a sidewalk, and eventually crossed a lawn toward a home, where he passed out under a holly bush. He stated that he went under the bush “so nobody could see me drunk.” His last recollection was “getting cold, and trying to get warm.”

Around 10:40 p.m., Jessica and Michael Sommerville were walking together when they discovered Brian Betancur lying on the ground. Ms. Sommerville testified that she saw another boy stumble away from Brian as they approached. Ms. Sommerville did not recognize Brian, and she began to question him. She testified that Brian did not appear to be aware of the cold weather, even though he was only wearing a tee shirt. In addition, his speech slurred at times during their conversation, although at other times it was clear. Because the situation appeared unusual, Mr. Sommerville called 911 and reported finding a boy lying on the ground.

Both paramedics and the Montgomery County Police Department responded to the call. Officer Todd Uvary, the first officer to respond, saw that Brian Betancur “was extremely intoxicated” and had vomited and urinated on himself. He was told by paramedics that Brian was suffering from hypothermia and a possible alcohol overdoes. Both Sommervilles told the police about the other boy they had seen, and Ms. Sommerville described his clothes. She also told the police that he stumbled away and sounded like he was vomiting, although Oscar later denied being sick. Officer Uvary communicated this information to the next two officers to arrive, Officers Holland and Camp. Concerned about the possibility that another intoxicated, lightly clothed boy could be outside, the three officers circled the neighborhood for approximately twenty minutes, using spotlights mounted on their cars to look in yards. At least one officer also got out of his car with a flashlight and looked in back yards.

As the officers were unsuccessful in the initial search, Officer Camp called a sergeant for advice and was told that it would be acceptable to bring a canine unit to the scene. Officer Camp called one of the appellants, John Greene, who was dispatched at 11:27 p.m. When Greene arrived, the other officers told him that Oscar was last seen approximately an hour earlier and that they had already made an unsuccessful search on foot and by car. Greene also was told that Brian had been taken by ambulance to the hospital for possible alcohol poisoning and hypothermia.

Greene decided to use his patrol dog, Carter, an animal trained to find individuals and to bite them when he came in contact, to make a quick search for the missing boy. While Greene normally would have used a bloodhound to perform such a search, his bloodhound was out of service with a knee injury. Because the police department's other bloodhound was off duty, Greene estimated it would have taken approximately another hour for it to respond. Additionally, because no scent item was available, a bloodhound search would have been difficult even if one had been available.

Greene also evaluated several other factors in reaching his decision. He considered that there was no definitive evidence that anyone was actually missing or endangered. However, if anyone was in fact missing, the cold weather, the presumed intoxication, and the elapsed time were all of serious concern. Greene also realized that no criminal suspect attempting to evade capture was involved, making it likely that he would see anyone before a dog got close enough to bite.

After deciding to use Carter to search, Greene put the dog on a fifteen foot lead. He did not muzzle Carter, and there is a factual dispute as to whether a muzzle would have significantly limited Carter's tracking ability.

Greene took Carter to the last point where Oscar was reported seen and commanded Carter to “track.” Carter cast about looking for a scent and then began to track down the sidewalk. Greene began to call out to Oscar, saying he was there to help and to take him home. Oscar states he never heard anyone, but the district court gave no credence to his assertions because it recognized Oscar was inebriated and not in a condition to hear. After tracking a short distance down the sidewalk, Carter turned sharply across a yard and went into a holly bush where Greene could no longer see him. Greene did not interpret the turn as indicating that anyone was close. The lead went slack, and only then did Greene realize that Carter had found Oscar, who was asleep. By the time Greene realized what was happening, the dog had already bitten Oscar's lower right leg.

Greene testified that he did not verbally call Carter off because Oscar was struggling, and Greene was concerned that if the dog released he might re-bite Oscar's face. Instead, Greene walked up the leash and physically removed the dog. While this was happening, the dog pulled Oscar some five or six feet…. Oscar suffered two lacerations on his lower right leg just above the ankle, one approximately 4.25 inches and the other 1.5 inches long.

The injuries to the boy’s leg resulted in a permanent disruption in sensation around the scars. He will have to wear a protective ankle brace for athletic activities indefinitely.

Oscar’s father, as Oscar’s guardian, sued Officer Greene and Montgomery County, both of which moved for summary judgment, which the district court denied. The defendants appealed the denial.

Judge Wilkinson first concluded that a seizure had occurred, noting that a seizure can take place “if police purposely detain a person but somehow use more force than intended.” Citing Supreme Court dicta in Brower v. County of Inyo, 489 U.S. 593, 109 S.Ct. 1378, 103 L.Ed.2d 628 (1989), the Fourth Circuit said that as long as the instrumentality (here, a dog) was intended, a seizure occurred even if the degree of the instrumentality’s effectiveness was unanticipated.

Officer Greene chose to use a dog conditioned to bite its target when found and thus cannot claim that there was no seizure when the dog he set in motion behaved exactly as it was trained to do.

The court noted that the handler believed the boy was not eluding pursuit and would likely be out in the open and visible before a dog could bite him. The Montgomery County Police Department guidelines allowed the use of patrol dogs to search for missing persons.

Nevertheless, the court concluded that there were factual questions that made summary judgment on the excessive force claim inappropriate. Why was the dog not muzzled? Why was a long (15 ft) leash used? Should the officer have recognized from the dog’s behavior that it was close to the boy?

The officer argued that the dog would not smell inside of a muzzle. He argued that the dog could not cast properly without a long lead.

Prior cases have referred to different lengths of leads. In Trammell v. Thomason, 559 F.Supp.2d 1281 (M.D.Fla. 2008), the officer used a six-foot lead to pursue a criminal, while in Peterson v. City of Federal Way, 2007 WL 2110336 (W.D.Wash. 2007), the handler used a 30-foot lead to search for a hit and run suspect with an outstanding arrest warrant.

Finally, there is a dispute over when a reasonable officer should have realized that Carter was close to locating Oscar. Officer Greene testified that he did not realize that Oscar was near when his dog reversed course and cut across the yard right before entering the holly bush where Oscar was lying. Plaintiff's expert, however, stated that the shift in course was significant and that a reasonable officer should have realized what was occurring.

The court felt that cases where a dog was released from a leash in pursuit of a criminal were not analogous in that letting a dog run free, knowing that it would bite its target when found, was a sufficiently different situation as to provide no useful guidance.

The International Association of Chiefs of Police (IACP) has a policy explicitly allowing the use of police canines to track missing persons so long as the dogs “remain on a leash of sufficient length to provide a reasonable measure of safety to the subject of the search without compromising the canine’s tracking abilities.” In a concepts and issues paper from 1992 (revised 2001), Law Enforcement Canines, the IACP adds that “caution must be taken when using law enforcement canines to track children or other civilians who are simply lost.”

The court held that Officer Greene was entitled to qualified immunity. State law claims survived, however. Judge Michael dissented on the determination that qualified immunity applied, noting the dangers of using a dog taught in the bite-and-hold method.

Melgar v. Greene, 593 F.3d 348 (4^th Cir. 2010). On remand, the federal district court declined to accept jurisdiction on the state claims and the case has moved to the state court system.

The Dogs of the Night Watch

In the urban centers of northern Europe in the Renaissance, a lowly and lonely profession was that of the night watchman. Those wandering the dark streets at night could often be presumed to be up to no good and night watchmen were usually armed against the dangers. It is therefore not surprising that night watchmen would acquire dogs to add the animals' senses to their own, as well as to combine the jaws of dogs with the weapons of their arsenels.

The title page of a book by Thomas Dekker printed in 1608, reproduced here, shows a night watchman of London carrying a lantern and a pike and followed by a dog. The dog, more alert than the master, has turned backwards towards a sound or a threat, its face showing almost human suspicion if not anger. No leash is depicted but the dog's collar appears unnaturally lifted towards the front. Perhaps the leash was left out because the artist wanted the teamwork of the pair, rather than a leather strip between them, to intertwine their fates. Or perhaps there never was a leash and I'm getting overly creative in my interpretation.

A woodcut from not too much later shows a night watchman of Antwerp subduing a criminal using just such a pike and a dog. The dog is biting the criminal in the leg while the watchman prepares to stab the man in the buttocks. Schoon and Haak, in their book, K9 Scent Identification, reproduce the woodcut and a greeting card from the night watchmen of Leuven in 1786, showing five men following or being followed by their dogs. These authors suggest that the companions of the night watchmen may have been the first police dogs and I have found no evidence to disprove this idea.

The dogs in these seventeenth century depictions are all medium to large, unlike the dogs leading blind men that I have described in prior blogs (October 9, September 14, July 19). Although the relative size of the dogs may have been adjusted for the artists’ purposes, it does seem that guard dogs were generally large, while guide dogs were small because of the poverty of their masters and the difficulty they would have had in feeding and caring for the animals.

Some of the dogs of the night watchmen may have been trained to attack. Ulysses Aldrovandus, in his natural history, De Quadropedibus, printed in 1621, writes that war dogs were trained as follows:

"The [war] dog ought to be trained up to fight from his earliest years. Accordingly some man or other is fitted out with a coat of thick skin, which the dog will not be able to bite through, as a sort of dummy: the dog is then spurred on against this man, upon which the man in the skin runs away and then allows himself to be caught and, falling down on the ground in front of the dog, to be bitten. The day following he ought to be pitted against another man protected in the same manner, and at the finish he can be trained to follow any person upon whose tracks he has been placed.... Blondus is even of the opinion that from time to time it is a good thing to go for this dog with drawn swords."

Aldrovandus reports that war dogs were more common in Spain than elsewhere in his time, and there are records of their murderous use by conquistadors in the New World. Stephanitz cites the 1473 edition of Mynsinger as stating that dogs were taught to "stand up to a man, who was clothed in a stout coat of skins lest the dog should bite him during his education."

Rembrandt’s Night Watch, displayed in the Rijkmuseum in Amsterdam, contains the figure of a dog towards the lower right of the painting. The dog was pointed out to me more than a decade ago by Milton Bellis when we stood beside the painting the night of a reception at the museum for the International Swaps and Derivatives Association. Milton, once a UPI correspondent in post-WWII Europe, knew some of the scholarship on Rembrandt's painting. The painting, earlier known as The Company of Frans Banning Cocq and Willem van Ruytenburch, may have nothing to do with night watchmen. The dog, the only animal in a painting of 34 people, barks at a drummer. It has been suggested by the art historian Georges Boka that the dog in the painting is a symbol of death. At a time when one could not turn on a light bulb in the night perhaps it was easier to imagine a dog barking at a soul searching for the boatman to cross the final river.

The tradition of night watchmen using dogs may have continued until the beginning of formal canine units in police forces. Policemen who used dogs generally bought their own initially, something mentioned in a number of nineteenth century and early twentieth century U.S. legal cases. J.J. Sullivan, official historian of the New York City Retired Transit Police Officers' Association, has found a notation in the records of the NYC police for 1853 that may indicate the police had in that year purchased "1 dog." It is not clear what the police department, almost 50 years before the first police canine units on record, would have wanted with a dog. Dogs were known to be used to guard warehouses and armories in the nineteenth century, and it is possible that some such use was being made of the dog.

Canine Remote Explosive Scent Tracing, Long Used in Europe for Screening Air Cargo, Continues to Be Tested in U.S.

Federal law mandates searching checked luggage, which may be done by canine teams, certain equipment, and other means, but luggage is not the only thing that goes into the hold of a plane. Air cargo also goes there. As recent events have made clear, cargo may not be screened as effectively as luggage. Although Congressional and Administrative policy has been to increase the number of explosives detection canine teams at U.S. airports, one of the more sophisticated explosives detection approaches awaits implementation in the U.S. despite widespread use in Europe.

A landmine detection methodology first developed in South Africa in 1985 (see blog of May 29, 2009) has in the last decade been adapted to sample air cargo for explosives. This method, called remote explosive scent tracing (REST) or sometimes remote air sampling for canine olfaction (RASCO), involves using dogs to sniff air samples at stations that are located in sterile rooms, much like those used in advanced scent identification procedures. The samples are extracted from cargo containers, or from under the plastic wrapping that holds a large number of packages together for shipment, using a suction device so that the sample presented to the dog comes from a confined airspace. An alert by a dog has a high probability of identifying the presence of an explosive among the items within the confined airspace.

Dogs are not the only animals used in REST work. One organization involved in removing landmines in Tanzania and Mozambique has had considerable success with rats.

Remote explosive detection is particularly useful with cargo because of the fact that unbundling materials being shipped together is both expensive and time consuming, and in some cases, such as with pharmaceuticals, can damage or destroy a shipment. About 12% of air cargo in the U.S. travels on passenger planes, but about 16% of air cargo coming into the U.S. reportedly comes on passenger planes. Air cargo operators in the U.S., such as FedEx and UPS, tend to have dedicated cargo fleets, and some passenger airlines, such as Northwest and United, also have dedicated cargo fleets. Overseas, about 22% of air cargo travels on passenger planes. It thus appears that over 80% of air cargo in the U.S. is not subject to the screening requirements that apply to cargo placed in the holds of passenger planes, even assuming the latter requirements are consistently met.

Use of REST in Europe
In 2004, a commercial system began to be used by agencies of the governments of France, and the UK approved it for screening cargo. The Netherlands Ministry of Justice and Military Police approved it in 2006. (See written question of Jeanine Hennis-Plasschaert, a member to the Dutch House of Representatives, to the EC, February 28, 2008.) REST is also used in the Amsterdam Schiphol and Johannesburg airports. The picture (courtesy DiagNose) shows a dog checking stations in a REST system.

In 2007, the Government Accountability Office published a report on aviation security, Federal Efforts to Secure U.S.-bound Air Cargo Are in the Early Stages and Could be Strengthened. The GAO discussed remote scent tracing:

"[T]wo European countries [presumably England and France] are currently using canines in a different manner than TSA to inspect air cargo for explosives. Specifically, these countries are using the Remote Air Sampling for Canine Olfaction (RASCO) technique, which involves the use of highly trained dogs to sniff air samples collected from air cargo or trucks through a specially designed filter. The dogs sniff a series of air samples to determine whether or not there is a trace of explosives and indicate a positive detection by sitting beside the sample. According to foreign government officials representing two of the countries that use this technique, tests to determine the effectiveness of this practice have shown that RASCO has a very high rate of effectiveness in detecting traces of explosives in cargo. According to foreign government officials, this inspection method can be used on cargo that is difficult to inspect using other methods, due to size, density, or clutter, and does not require the breakdown of large cargo pallets. Further, officials stated that the dogs used in RASCO do not tire as easily as dogs involved in searching cargo warehouses, and can therefore be used for a longer period of time…. According to TSA officials, while the results of previous agency tests of RASCO raised questions about its effectiveness, they continue to work with their international counterparts to obtain information on the feasibility of using RASCO to inspect air cargo. TSA officials stated that the agency has not yet determined whether RASCO is sufficiently effective at finding explosive in quantities the could cause catastrophic damage to an aircraft and whether this technique will be approved for use in the United states."

In a 2010 report on air cargo security, the GAO referred to RASCO again, but made no mention of its possible implementation in the U.S. The GAO did state that RASCO might "produce different results from TSA's screening standards," but it is not clear if this was a reference to any research TSA had conducted.

The Scientific Working Group on Dog and Orthogonal detector Guidelines (SWGDOG), which suggests industry standards on the training and uses of police dogs, said in its 2007 Guideline SC7-Research and Technology that independent scientific evaluations of the capabilities and limitations of the REST systems are essential. A 2010 proposed revision includes the same urgent recommendation. In Norway, Rune Fjellanger, the preeminent researcher on the method, reported 95% detection reliability eight years ago, thus meeting the U.S. military's standard for explosives detection dogs.

How Effectively Is Air Cargo Screened Before Going on Passenger Planes?
The bombs hidden in printer cartridges found at airports in East Midlands and Dubai last week contained PETN (pentaerythritol tetranitrate). East Midlands Airport is the UK’s busiest pure cargo airport, handling 300,000 tons of flown cargo every year. It is the UK hub for DHL and UPS, and it was in a UPS package that the disguised explosive device was found. News reports stated that the bombs had been on passenger planes during their journeys.

The Implementing Recommendations of the 9/11 Commission Act of 2007 (PL 110-53, August 3, 2007) contained provisions (§ 1602) on the screening of cargo carried aboard passenger aircraft, which required that, by August 2010, “the Secretary of Homeland Security shall establish a system to screen 100 percent of cargo transported on passenger aircraft operated by an air carrier or foreign air carrier in air transportation or intrastate air transportation to ensure the security of all such passenger aircraft carrying cargo.” Screening may include various technologies including “explosives detection canine teams certified by the Transportation Security Administration.” The Act also encouraged the use of blast-resistant cargo containers (§ 1609).

In 2008, the GAO reported that there were 370 TSA-certified explosives detection canine teams cross-trained to work in multiple aviation environments, including air cargo. Teams specializing in air cargo were located primarily at the 20 airports that receive approximately 65% of the air cargo transported in the U.S. In June 2010, the Transportation Security Administration issued a statement, 100% Air Cargo Screening: Path Forward, admitting that “screening 100 percent of cargo inbound to the US will not be attainable by industry by the August [2010] deadline, however TSA is committed to ensuring industry obtain that level of security as rapidly as possible.”

A Report to Congress in 2007 noted that it was not only the amount of cargo that was shipped on passenger airlines that was a problem for screening everything, it was also the complexity of the system. About 50 air carriers transport air cargo on passenger airlines from nearly two million shippers every day. Approximately 80% of the shippers use freight forwarders who operate about 10,000 facilities in the U.S. The TSA has, therefore, relied on a strategy of establishing databases of known shippers and freight forwarders and comparing shipments to entities labeled as approved in databases. When a match is not found, a targeted inspection can be initiated. The report stated that TSA policy is to “screen, inspect, or otherwise ensure the security of all-cargo aircraft is to be established as soon as practicable, but sets no specific deadlines or time frame for compliance.” When air cargo arrives in the U.S. from abroad and is transferred to a domestic passenger flight, TSA's policy is that this cargo "must be made available to TSA canine teams when these teams are present in cargo facilities."

At present, when canine teams inspect cargo, the procedure primarily involves running a dog through a loading area or having it stand beside a conveyer belt where it sniffs the packages as they pass. One bomb dog handler advised me that sometimes air cargo facilities are concerned about a shipment wrapped in plastic but do not want the wrapping unbundled, so he slits the package on each side allowing the dog to sniff the air inside the wrapping. He acknowledged that a remote air scenting system would have been preferable.

In a 2009 report reviewing TSA’s progress in screening, the GAO said that there were only 37 canine teams dedicated to air cargo screening, but added that there would soon be 48 more, meaning that there are now somewhere around 100 dedicated air cargo sniffing dogs. The report said that TSA was attempting to identify peak cargo delivery times during which dogs would be most helpful for screening. This suggests that packages arriving at non-peak times may not be screened.

EU Requirements
The European Commission provides standards for aviation security in the EU. After April 2009, European Commission Regulation 272/2009 allows screening of passengers and employees at checkpoints to be performed by dogs, as well as cabin baggage and baggage carried at a checkpoint, hold luggage and other cargo and mail to be loaded into the hold. Vehicles and the aircraft themselves may also be searched by explosive detection dogs.

In Regulation 573/2010, the Commission elaborated considerably on explosive detection dog requirements. Dogs are to be single purpose dogs and are to be taught to give a passive response. The EDD and the handler must both be approved independently and in combination. Both are to receive initial and recurrent training. Recurrent training is to occur at intervals of no longer than six weeks. Recurrent training sessions are to be at least four hours long. Training records are to be kept on both the EDD and the handler. Finally, the Regulation provides that security screening may involve free running or remote explosive scent tracing. REST may also be used for screening cabin and carry-on baggage, vehicles, aircraft, in-flight supplies and airport supplies. Dogs used in REST work can have two handlers, presumably a recognition that dogs can do this work for longer periods than is the case in traditional sniffing assignments.

Where Does TSA Stand on Implementing REST?
A 2008 Report to Congress stated that TSA was working with the Department of Homeland Security on operational procedures to improve canine detection capabilities. The Report stated: "One technology being examined is Remote Air Sampling Canine Olfaction (RASCO) sensors, which can provide a concentrated sample from a container for a canine to inspect and has been used extensively in Europe. The DHS project plans to expand this concept to include chemical sensors carried on jackets worn by the canine that will be capable of transmitting data to remote monitoring stations."

Perhaps TSA's efforts to combine the dog's sniff with a chemical sniff explains the delay in implementing REST in the U.S.

The Technical Support Working Group, an interagency program for research and development into counter-terrorism measures, has posted a Combating Terrorism Technical Support Office 2009 Review. A section of the Review on "next-generation canines" indicates that TSWG is exploring "technologies that support and enhance canine detection." TSWG is under the Combating Terrorism Technical Support Office (CTTSO), which is under the Assistant Secretary of Defense for Special Operations/Low-Intensity Conflict & Independent Capabilities. Proposals for RASCO testing were invited by CTTSO in October 2008 (Broad Agency Announcement 09-Q-4500). The following describes the tests that were sought:

"The performing organization will be required to design, develop and operate a RASCO test-bed for air cargo screening. This test-bed shall be a model of activities of an air-cargo facility which has deployed the RASCO screening process. A warehouse where cargo can be assembled into air shipping configurations and then arranged for sampling will be required. The warehouse shall also have a separate area for canine interrogation of the samples. The test-bed shall have separate storage areas for used and unused commodities and shall have storage facilities for bulk amounts of explosives. The investigating entity shall be fully licensed to receive, store, handle and ship bulk explosives. (This can happen up to two months after award if necessary). The site shall have the capability to accept and ship large amounts of air cargo commodities in their shipping configuration or broken down as required. The contractor shall have knowledge of U.S. air cargo screening requirements. The contractor shall procure and train canines to detect trace amounts of explosives using a government furnished protocol. Canines must be maintained for long periods of time at a location remote from explosive storage. It is noted that the training procedures for RASCO may not be the same as for other types of canine detection. These training procedures will be provided by the government. The training aids [generally samples of explosives] used shall be fabricated by the performer using established procedures. Adequate facilities shall be available for the formulation of training aids. The procedures for fabrication will be supplied by the government. The option to use the test-bed as a permanent facility for training and testing is desirable. Authentic air cargo samples must be taken and used for training purposes. The awardee must be able to supply these samples to the test-bed. A location near an air cargo hub is desirable."

It would seem then that testing is going on, and may have been going on for several years.

Conclusion
It is unlikely that the Transportation Security Administration would make a public statement regarding a specific commercial provider, but it should acknowledge the existence of the approach and place it in an advisory, if not a regulatory, context. REST has been tested by various countries and at various cargo facilities, both air and maritime (as well as for downloading air samples from trucks in some locations), and the risks associated with air and marine cargo argue for implementation as soon as is practicable.

Addendum. I thank readers for sending me comments and additional leads regarding this subject since I first posted the blog two days ago. Perhaps the biggest advantage of an increased readership is that people are happy to point out errors and oversights. Even before I opened the New York Times this morning (November 11), I was directed to the story John Burns on A6, Yemen Bomb Could Have Gone Off at East Coast, stating that the package in Britain had been missed by sniffer dogs and explosives-detection equipment. I have been advised that there is no REST system at the East Midlands cargo facility, so if this is where dogs did not alert to the package, they must have been taken past it by a handler.

Second Addendum. Steve Lord, Director of Homeland Security and Justice Issues with the Government Accountability Office, testifying before the Subcommittee on Transportation Security of the House Committee on Homeland Security, on March 9, said that the Transportation Security Administration had, as of February 2011, 113 dedicated air cargo screening teams working at 20 airports, but would be adding seven additional teams. He also stated that a pilot program at two certified cargo screening facilities (CCSFs) was testing the feasibility of using private canine teams to inspect air cargo. Certain air cargo is not screened by dogs, however, as is made clear from the following portion of Lord's statement:

"TSA has not approved or qualified any equipment to screen cargo transported on unit-load device (ULD) pallets or containers—both of which are common means of transporting air cargo on wide-body passenger aircraft—both domestic and inbound aircraft. Cargo transported on wide-body passenger aircraft makes up 76 percent of domestic air cargo shipments transported on passenger aircraft. The maximum size cargo configuration that may be screened is a 48-by-48-by-65-inch skid—much smaller than the large pallets that are typically transported on wide-body passenger aircraft. Prior to May 1, 2010, canine screening was the only screening method, other than physical search, approved by TSA to screen such cargo configurations. However, effective May 1, 2010, the agency no longer allows canine teams to screen ULD pallets and containers given TSA concerns about the effectiveness of this screening method for those cargo configurations."

Lord states that TSA is continuing to test other screening technologies for ULDs. It appears that cargo may remain the most significant hole in passenger airline security.

On March 14, 2011, DiagNose announced that its trademarked system is now in use at the Amsterdam Schiphol Airport.

Third Addendum. Attachment 12-H to Regulation 573/2010 specifies size limits for consolidated consignments for explosives detection dog screening. The Attachment reads as follows:

“When screening cargo (including the cargo consignments of express parcels), the consignment shall be made available for screening in a non-containerised packing. The height of consolidated consignments shall not exceed 130 cm in height and 100 cm in depth [just over 4 ft. x 3 ft. 3 in.], unless a single piece of consignment is exceeding such dimensions. The nature of each consignment shall be taken into account before the handler shall direct the EDD to each item and evaluate the reaction of the EDD. The EDD shall be able to access and sample odour from all pieces of cargo.”

This means that if a consolidated consignment can be sniffed from both sides, it can be up to 200 cm wide (about 6½ ft.). For consignments higher than 130 cm, a ramp can be used for the dog to sniff the top of the consignment.

At least one company providing canine services for cargo screening has requested additional guidance from the European Commission. The EU responded that existing EU legislation on explosive detection dogs can only be reviewed after it has been in place for a reasonable period of time, but if other industry stakeholders believed the need to be more urgent, the Directorate General on Mobility and Transport will investigate "at an earlier stage." So far this has not happened.
