Been pulled over twice in Manhattan for running reds - both times at intersections where there was no possibility of cross-traffic and there were no pedestrians.
1. I was coming down Broadway, crossing Astor around 10:00 a.m. on a Saturday, and it was the start of the worst morning ever: Five cops fanned out and waved me down. I was hung over and on my way to meet my girlfriend at the time to go with her to a doctor's appointment so as to split the cost of birth control pills. While the cop was writing the ticket, a friend of mine randomly wandered by and said he had an extra ticket to some big summer all-day concert that started at noon that day, and did I want to come? Of course I did, but I said, "Nah. I gotta get this ticket and go meet my girl." After getting the ticket I got hit by a car just below Canal (he turned right across me and his stupid car actually gave me a cut on my knee without fully knocking me over), then got a flat on the bridge, and when I finally got to my girlfriend's house, she told me she'd cheated on me the night before. I didn't pay for the birth control.
2. Working as a messenger, I crossed 41st street at 6th Ave. where it runs into Bryant Park. A bike cop pulled me over and I gave him a (polite) hard time, since there were no cars or people around just then. Finally, he asked me if I was working as a messenger and I said yes. He asked for my "messenger ID" and I said "whuh?" So instead of writing me a ticket for running a red light, he gave me some kind of code violation for "failure to produce messenger ID." He told me that if I got my company to make me an ID and brought it to court, they'd drop the thing, and that's exactly what happened. The judge was totally surprised that I actually had an ID and said, "Well, this is unusual! Case dismissed."
I was also nabbed twice in Cambridge, MA, for the same offense, but no amusing stories: Once I got a written warning, and the other time I got stopped with some other guy who also happened to be running the light on his bike at the time, and the cop wrote his ticket first, but let me go when he looked at my ID and saw that it was my birthday.
