I will say that a few weeks ago my wife got a warning in the mail from the BPD saying she turned left at a place where it is supposedly forbidden. She wasn't pulled over and neither of us see any places at the location where it says no left turn, but there isn't anything to fight because it was just a warning. Our theory was that the cop happened to be there and took her info down. It was certainly a strange thing, and the idea of a cop being too lazy to get out of his car and instead passively send in the mail is bothersome.
