- someone in a crowd smashing windows (police can't identify who)

- encircle the crowd and ask who is press

- person who was smashing windows (unbeknownst to the police) claims they are press

- person is escorted out

- person goes smashing windows somewhere else

If police can't identify who, they have no good justification for detaining anyone, much less everyone.

If the assembly is deemed unlawful because of threat of violence then they ask people to leave and if people refuse to disperse they can arrest them.

What would you change about this process?
