That's why it's called the "R" train

New technology can be a good thing.

A creep exposes himself to a woman riding the R train in New York City, and she takes a photo with her cell phone. Ha, ha, so far, so good. Then she posts it on the internet to try to get an ID of the creep. (Too bad there weren't, to paraphrase Dave Barry, a couple of guys named Vito on the train to have a word with the guy.)

The NY Daily News brings you the story with a tasteful cut of the photo. (Via Drudge.)
