even though the sample size was small and imo the test was setting the dogs up to fail, its still shocking at how miserably those k9 teams failed. i read another study where the k9 handler was falsely told that there was drugs in the room when the room was actually clean. in this case, the dog falsely indicated just because the handler themselves thought there were drugs there.
there is no doubt that these dogs are an invaluable part of the police department. if you want to look at it with the glass half full view then these dogs basically have a 0% failure rate since they always find the drugs. but with a false positive being so easy it makes them unreliable and they shouldnt be a walking search warrant. i wonder how a military dog would have done in this test?
