Dogs are smart at reading people -- they know how to figure out what their handler wants them to do -- and they'll get a treat for it. But, hey, let's fill the airports up with them. Who cares about a little racial profiling, right?

A study of "false positives" involving drug-sniffing police dogs suggests some police forces may be using canines to do an end-run around constitutional protections against search and seizure, and may be profiling racial minorities in the process.
A survey of primarily suburban police departments in Illinois, carried out by the Chicago Tribune, found that 56 percent of all police searches triggered by a drug-sniffing dog turned nothing up.
But, perhaps tellingly, that number jumped to 73 percent when the search involved a Latino subject -- meaning that nearly three-quarters of all dog alerts on Latinos turned up no contraband. The study covered a two-year period from 2007 to 2009.

But civil liberties advocates smell a rat, and say this is evidence that police are using canines to carry out racial profiling and unjustified searches. And dog-training experts say the problem stems at least in part from an almost complete lack of standards for police dogs in the US.

Lawrence Myers, an Auburn University professor who studies police dogs, told the Tribune that residue from long-gone drugs isn't the only way a dog can give a false positive. Dog handlers can trigger a false positive from a dog by walking it around a car too many times, or too slowly, giving the dog a cue that a certain behavior is expected.

"We've seen a national outcry about being frisked and scanned at airports," ACLU attorney Adam Schwartz told the Tribune. "The experience of having police take your car apart for an hour is far more invasive and frightening and humiliating."
