Why doesnt anybody ever get angry with the photographers of these sorts of things, they are as much a part of it as the police for standing there and just watching it. At the minimum the they could alert the police they have a camera, which would be enough to deture any over use of restraint, so are they not accomplices?
Have you even seen the video? The AP journalist with the camera shows one of the officers his credentials and says he's working, and the cop shoves him around, curses him out and tells him to go home. Displaying the camera didn't help, at least not in this situation.
