Rolling a read light in a group. I was the front man and was polite and just responded with "Yes, Sir", "You are completely correct officer", etc..... This was a rich neighborhood on the north shore of Long Island, where the residents hate the Sat & Sun morning cycling clubs riding "their" streets, thus the cops had a hard on for cyclists and would await at certain intersections. We were wrong, but got a warning. I think the cop didn't want to write 10 ticket, too much work.
