Keach Hagey, the short-lived former Village Voice press columnist, is suggesting over on her blog at CBS News that yesterday's video of an average white man being assaulted by a group of black teenage girls on the A train could be a hoax. Why? Because the girl who filmed it was an aspiring filmmaker who claimed, at first, she didn't know the assailants but, right after being interviewed by The Smoking Gun, deleted her YouTube page! Oh, wait. that doesn't mean anything! In related news, Katie Couric's viewership on CBS is down a million viewers over a year ago.
