I guess I fail to see why anyone should treat them like shit unprovoked. Most of these traffic cops are just trying to do their job, and the more you "push" it/them, the worse the situation becomes. For a simple traffic stop, it's worth considering that it might just be better to let them do their job and then get the hell out of there. Don't give them more of a reason to take it any further! Then again, that's just my opinion, and it might be because I've seen a lot of LE who are genuinely good people just trying to do their job and actually HELP people. Unfortunately, that's not a universal thing, but it's also not a universal thing for all cops to be assholes who deserve horrible things.
