Yes, it's gotten to the point where everyone needs to have a camera at all times. I know and you know, of course, that the real solution is for everyone to stop being a douche, but the odds of that are just... it's not gonna happen.
Incidentally I was pulled over twice last week (first two times ever). I promptly informed both officers that I was licensed to CCDW and that I had a firearm in the car. One told me that if I attempted to leave the vehicle he would shoot me without question, the other one simply laughed and said as long as I left it where it was we'd have smooth sailing. There are real dickheads in every profession so... I gotta say though, it felt really uncomfortable having the first one threaten to shoot me.
