This was the end of a police chase and the Sgt. doesn't want video coverage from a credentialed member of the press. The photog asks how far to move back but the sgt. says no you can't shoot it at all. Notice the road is open to traffic, there are people without a camera that are standing there and even some kids walk straight through the scene. The photog moves a block away and shoots from the next street over and that's when he's arrested and charged with Obstruction of Governmental Administration....how can you obstruct from a block away.
