I've never had but one bad experience with a cop, but that one left a pretty bad taste in my mouth.

But I will say this, I am treated much better now that I'm in my 40s and driving a nice automobile than I was in my 20s. My attitude hasn't changed either. It just seems to offend them a lot less that I don't give an inch. And I'm not talking about being impolite, just not obsequious. Of course, even cops understand that forty some year old white guys, dressed nicely in nice cars are not the ones to frick with.
