I've been pulled 3 times. First when I was 17 years old and got ticketed for doing 47 in a 35, or something like that. I was running late for school, had a head cold and had taken some meds that didn't agree with me so I felt like a freight train. I was lucky they didn't write me up for worse. Second time was for doing 70 or so in a 55, midnight on the interstate. The lady let me off with a warning because I was only a mile or so from my apartment and didn't seem like a troublemaker. Third time was also around midnight/1am, I pushed the reasonable boundary when going through a light that had just turned yellow. My fiance and her puppy were riding shotgun and I was taking her home after working in our new house preparing to move in before our upcoming wedding. Again, got off with a warning because I owned up to blowing through the light and didn't seem to be causing any trouble. I think they were really just trying to catch DUI's that night.
Oh I did get checked for window tint at a traffic stop once, cop was being a jerk in a town where the cops were known to be jerks. He was a pompous ass, wrote me a ticket that he said he would tear up if I got the tint fixed prior to court, which I did and he still charged a fine.
Most of my interactions with police have been fine, and the police that I know personally are all stand up people. I respect them and what they do.
