Oxy's right. I can tell you from experience. I was a participant in the riots of 68 UNTIL I saw at EVERY demonstration, people who instigated the demonstrators passing them bottle molotovs, paint, rocks, etc. etc. and look, oh, gee, I wonder why, their faces covered with scarves and irrecognizable. They are the ones who are rioting for rioting's sake and looking for anarchy.
