But the dog didn't bat an eyelid at the scent of your meat snack. See, dog noses are goddamn incredible. If it's drugs they search for, then that's the only thing they'll react to. That's why many districts spend as much as $36,000 per year to have K-9 units sweep their schools. Which is a shame, really, considering that drug dogs are accurate less than half the time.
"Just hand over the jerky and I'll pin it on the fat kid, alright?"
And we don't mean that the dogs miss a lot of drugs. They don't. We mean they result in a lot of innocent people getting searched. About 56 percent of the time, when the dog says, "Search this dude's cavities and trash his car, that man is as evil as a vacuum cleaner!" the person has done nothing wrong. What's more, they appear to be racially biased: If the person being sniffed is Latino, the success rate drops to 27 percent. The other 73 percent of the time, they're getting thoroughly and embarrassingly searched for doing nothing at all, just because a dog said so.

And yet dogs always insist they're colorblind.
