I've been pulled over twice. The first was total BS "rolling stop" when turning right on red. The cop came to the window and acted all shocked like, "didn't you see the light was red?!?" I said, "yes sir, I apologize." Gave him the license and registration, he went back to the car and came back like 5 seconds later and said, "please be careful," and let me go.
The second was legit, I ran a red and the cop was RIGHT BEHIND ME He pulled me over and looked at me like I had 3 heads and asked, "are you all right, sir?" I said, yes sir, I'm sorry but I was distracted for a moment." There was a lot of traffic at the time, so he just told me to pay attention and off we went.
