@tweetr - I hope your son rehabilitates himself and no longer pursues criminal interests. I'm sure Rogers County is much safer now that he's been investigated at the roadside.
If you want to amuse yourself you might check out studies on drug dogs taking cues, it's a thing.
Also check and see how many of those studies indicated that the cueing was unintentional by the officer. "Problem" is dogs are MUCH smarter than we are and they learn what we want -- and they give it to us in exchange for the reward we give them.
