Quote from: topia on February 14, 2012, 07:40 amI read recently (but forget where) that 80% of K9 positives were the result of handler suggestion. Like they gave the dog/human team a hippy with fake pot vs a square with real pot. Whether the stat is true or not I believe that the dog is merely a tool for the cop to search ya. And if they want to search ya they will.I'm not suggesting that handlers don't sometimes use their dogs unscrupulously, but mostly dogs just work. I've seen mythbusters where a dog finds packages of drugs inside a giant warehouse filled with millions of items, and that was when the package was disguised inside items with strong cover up smells. Like Oldtoker says, the key thing is that they can't keep it up for long and their powers of observation can't be automated just because you have a detection mechanism.
