Oh for heaven's sake. Just look at any comparison between "Occupy Wall Street" demonstrations (which almost always turned violent and ALWAYS left chaos and vandalism in their wakes) and the Tea Party, which, although there were some abusive behavior, almost always left their venues in better shape than they were found, limited their 'abuses' to words (crashing Obama-care rallies, etc.,) and did NOT trash police property and attack police or other officials.
...and Los Angeles is a prime example of just that.
