The Occupy movement may have been nominally non-violent, but in practice many people involved with it also engaged in violent property damage, and not just towards the property of banks or other ideological targets; there was also abundant violent and tinpot revolutionary rhetoric to go around.

I have zero sympathy for such tactics, whether practiced by Occupy or the Tea Party; the people who manipulate populist sentiment for political advantage are irresponsible jerks. And for those who suggest that this represents some sort of new totalitarianism, I invite you to go read the Wikipedia article on the Whiskey Rebellion of 1791.
