My take, in general: If the camera is catching officers telling everybody to stand back, to back the hell up, etc... Then the camera crew should be doing so as well. Including if they're professionals, because if they're pros the zooms on their cameras should be more than up to the task of recording something at 25-50' away.
If the police choose to interact with somebody, and NOT moving them away, said person is entitled to record at the distance that the officer chooses to interact with them at.
If somebody is obnoxious about moving away when the police tell them to do so, then perhaps they should maybe catch some trouble, whether they're video recording or not.
