Washington - Can you trust what a dog's nose knows? Police do, but the Supreme Court considered Wednesday curbing the use of drug-sniffing dogs in investigations following complaints of illegal searches and insufficient proof of the dog's reliability.
Justices seemed concerned about allowing police to bring their narcotic-detecting dogs to sniff around the outside of homes without a warrant and seemed willing to allow defense attorneys to question at trial how well drug dogs have been trained and how well they have been doing their job in the field.
"Dogs make mistakes. Dogs err," lawyer Glen P. Gifford told the justices. "Dogs get excited and will alert to things like tennis balls in trunks or animals, that sort of thing."
But Justice Department lawyer Joseph R. Palmore warned justices not to let the questioning of dog skills go too far, because they also are used to detect bombs, protect federal officials and in search and rescue operations. "I think it's critical ... that the courts not constitutionalize dog training methodologies or hold mini-trials with expert witnesses on what makes for a successful dog training program," he said.
"There are 32 K-9 teams in the field right now in New York and New Jersey looking for survivors of Hurricane Sandy," Palmore added. "So, in situation after situation, the government has in a sense put its money where its mouth is, and it believes at an institutional level that these dogs are quite reliable."
