Christopher Long, the Critical Mass cyclist pushed off his bike by a rookie cop—and captured on YouTube—is back at his job in Union Square's Greenmarket. He's not talking to press because there are pending charges against him of assault and resisting arrest. (They'll probably be dropped.) Meanwhile: investigation 2.0! Because of videos like this one, Police Commissioner Ray Kelly tells the Post that "Within the next two months, people will be able to send video and text straight to 911 to increase flow of information." Naw, they'll just hide them. Send all video footage straight to us. [Daily News]
