I've been pulled over by idiots with an attitude that proceeded to back themselves out on to a major highway (a no-no Mr. Policeman), and I've been pulled by Staties that were kind and had a sense of humor, one gave me a warning, the other gave me a ticket...I don't classify every cop here as one way. I think you have good and bad in every profession, from state to state. Sounds like you just got unlucky that day and caught one in a bad mood; doesn't mean that's how they all are.
I'll never forget the first speeding ticket I got that stuck (I'd gotten out of a previous one). I was in traffic, some idiot on my bumper, so I got aggravated and I sped up, got out of his/her way, and that's when we both passed a State Trooper. Well, the trooper pulled me, and the person that I was getting out of the way for headed on down the road. I was certain the cop would hear my plea and give me a free pass, so I even told him "Look, I was only speeding because the guy behind me was right on my a$$..." and he replied (and I'll never forget it, because he said it with almost a chuckle) "Well, was he chasing you?!"
I cracked, and smiled and said "No..." and got the speeding ticket...fair enough, speeding is speeding...
