It dawns on me that these sort of "protests" are being done, partly to destroy stuff and loot, but at some point, people in general will so stridently cry for a crackdown so ANY protest, actually conducted peacefully, will be shut down, and violently so.
If there isn't violence, it only takes a half dozen or so with some IEDs to make it look like it's a general thing.
Of course, when and where and against whom the rules are applied depends on whether your group is officially backed by Kameltoe's bailout bunch.
