All I know is you burn a building, that's a reason. You throw objects at cops, that's a reason. You physically assault a cop, that's a reason. You can't do these things and then throw your hands up and get away with it. When you are doing these things then you are NOT protesting, you are rioting. The Feds gave the opportunity to disperse on their own. It was ignored over and over. The feds DO NOT have to be nice and give anyone rioting a chance to leave. But they did. Play stupid games, win stupid prizes like batons, pepper spray, arrest.
