I’m not sure that what happened before really matters that much. Most of the footage released shows that the members of the public didn’t represent a threat to the police or other member of the public when the police used (what appears to be) unnecessary violence against them.
It also doesn’t really matter if the ones who had violence used against them were the same people who broke the female officer’s nose either. The police are there to uphold the law and arrest anyone who has broke the law. They’re not there to exact vigilante justice on people because one of their own got smacked.
I’d be surprised if the bizzies got away with it what with it all being on camera. But, saying that, I’d be equally surprised if anything happen to the bizzies. Because, well, just because.
