Nguyen, State of Florida v. Harris and Similar Cases Summary: Before carrying out a warrantless search of a person or their property, police officers need to have sufficient information concerning involvement in possible criminal activity to meet the “probable cause” criteria. In U.S. v. Place, the Court held that dog sniffs of vehicles, stopped for lawful purposes, were not a search. Courts have allowed police to search a vehicle or item after a trained narcotics dog indicates that it contains contraband as the positive indication establishes “probable cause”. The criteria many courts use to assess the reliability of the dog, the fraction of positive identifications in which drugs were found, however, is the predictive value of a positive test (PVP). While related to the two proper measures of the accuracy of a screening technique, the PVP also depends on the prevalence of contraband in the places the dog has examined. It is will be seen that the same PVP can arise in situations where an accurate dog sniffs items with a low prevalence of contraband or when a much less reliable dog examines items with a high prevalence of drugs. It will be seen that it is mathematically impossible to estimate the two accuracy rates of a narcotics dog from the data typically submitted by the state to show the narcotics dog is reliable. The problem arises because one needs three equations to estimate the prevalence and the two accuracy rates but the data only provides two. These issues will be illustrated on data from actual cases. Rather than continuing to rely on an inappropriate measure of the accuracy of dog sniffs, courts should require more information concerning the accuracy of dogs in their training sessions and in the field as well as better information on the prevalence of drugs in commonly occurring settings, e.g. vehicles stopped for routine traffic violations or items examined after police have received a “tip”. Then the legal system would have sufficient information to estimate both measures of accuracy of a narcotics dog and its PVP, which would assist courts in determining whether the police had “probable cause”.

Author: American Civil Liberties Union of Illinois Title: Racial Disparity in Consent Searches and Dog Sniff Searches: An analysis of Illinois traffic stop data from 2013 Summary: Throughout Illinois, there is a dramatic racial disparity in police use of so-called "consent searches" and dog sniff searches during routine traffic stops. This is shown by a decade of government data about consent searches collected and published under the Illinois Traffic Stop Statistical Study Act of 2003 ("Study Act"), and the first two years of such data regarding dog sniff searches. For example, the recently published 2013 data shows that Illinois State Police ("ISP") troopers are 2 1/2 times more likely to consent search Hispanic motorists compared to white motorists, but white motorists are 2 1/2 times more likely than Hispanic motorists to be found with contraband during such ISP searches. Likewise, ISP troopers are more than twice as likely to dog sniff Hispanic motorists compared to white motorists, yet white motorists are 64% more likely than Hispanic motorists to be found with contraband during a trooper's search based on a dog alert. These disparities are a clear sign that the ISP's threshold to conduct consent searches and dog sniff searches is far lower for Hispanic motorists than for white motorists. Such racial disparate impact against black and Hispanic motorists likewise exists statewide, and in stops by the Chicago Police Department and other local and county police agencies. This ACLU of Illinois report begins with a brief discussion of the Study Act, upon which this report is based. It then presents findings of substantial and ongoing racial disparate impact in the use of consent searches and dog sniff searches during routine traffic stops.

Author: King, Douglas Title: Moving to Minimum Force: Police Dogs and Public Safety in British Columbia Summary: Every two days someone in British Columbia is injured by a police dog. Police Service Dog (PSD) bites are the leading cause of injury at the hands of municipal police, exceeding by a factor of six injuries incurred by all other forms of non-lethal force, including batons, pepper spray, fists, and Arwen rounds (beanbags). Unlike other police impact weapons such as fists and batons, police dogs are unique in their tendency to inflict permanent injury. Despite heavy reliance on PSDs and the high rates of injury associated with their use, there are no uniform policies specifying when a police dog unit should respond to a call, the types of situations that warrant the deployment of a dog, or how records relating to police dog deployments and related injuries should be kept. This study relies on in-depth case studies from Pivot Legal Society's client base, as well as case law and statistical data provided by the Office of the Police Complaints Commissioner (OPCC) and the RCMP. This study evaluates the prevalence of PSD bites, the impact that training and deployment practices have on the frequency and severity of injuries, and how PSDs fit into the Canadian National Police Use of Force Framework (NUFF).

Author: Schiavone, Ann Title: K-9 Catch-22: The Impossible Dilemma of Using Police Dogs in Apprehension of Suspects Summary: In the past several years, the city of Pittsburgh, Pennsylvania has seen two canine police dogs (K-9s) killed in the line of duty, Rocco in January 2014, and Aren in January of 2016. Both were killed by stab wounds while attempting to apprehend suspects. The man who killed Rocco received significant jail for stabbing and killing the dog, while the man who killed Aren was fatally shot as a direct result of his actions toward the canine. While Rocco was vocally celebrated in the community, and sympathy primarily focused on the canine, the deaths of Aren and the suspect who killed him, Brian Kelley, Jr., led to a very different response. In the aftermath of the 2016 incident, there was significant vocal outcry from a variety of advocates (for both humans and animals) concerning the injustice of using K-9 officers to apprehend suspects and calling for a ban on such practices. Certainly, Pittsburgh's experiences are not unique, although they present a vivid backdrop for the discussion of whether K-9s should be used for apprehension of suspects and under what circumstances. This paper explores the legal and ethical questions surrounding the use of police dogs, specifically in the realm of apprehending suspects where a violent interaction between human and canine is inevitable. The Fourth Amendment allows the use of canine force against persons if "reasonable" under the totality of the circumstances, based on the officer's observations. However, that totality of circumstances does not take into account the very real and very reasonable fear response induced in humans by an animal attack, that in some cases compels the suspect to defend themselves and thus places the suspect at risk for further violence, and the police dog at risk for injury or death. Further, while any suspect may be compelled to resist or defend itself against a police dog, the historical usage of police dogs against African Americans, coupled with the deployment of police dogs more frequently in minority communities may tend to put African Americans at greater risk in this K-9 catch-22. Ultimately, the paper considers the question of whether, in light of human behavioral fear response to animal attacks coupled with examples of implicit racial bias, using police dogs in apprehension is ever truly "reasonable."
