I've gotten traffic tickets a few times. The cops weren't rude, I suppose. One was nice enough to hurry my ticket when he saw I was a teacher on my way to work.

The only bad interaction I've had with a cop was when BJ and I were teenagers. It was pretty late and we were on our way to one of those obscure places at the edge of town where teenagers go to drink and make out and the like when we ran into a dead-end. The area was under construction, and they were turning a through street into two cul de sacs. It was just a patch of dirt at the time and it was late so he just drove over it. A cop happened to be nearby, pulled us over, asked BJ to get out of the car, and just swore at and berated him for several minutes, telling him how he could "smurf up his life" and such. For driving over a patch of dirt.

It was just really irritating.
