I got hassled by a guy who said he was a cop one day, he got mad because I took the lane to keep him from violating the 3 feet to pass law (and the speed limit too). I figured it wasn't worth it before I saw the pistol in the holster on his belt (he was out out uniform, and wasn't in a cop car), and was glad when he showed his respect for the laws he's supposedly paid to uphold when he made an illegal turn to take off when he was done with his end of the conversation.
