American Apparel is notorious for using LA-based factories to produce all of its clothes so this doesn't even make sense, thanks rioters for sending a clear message!
Just so everyone is clear: the protesters (for the most part) weren't involved in smashing stuff, that was a separate group of people who also showed up so they could hide behind the anonymity and blend into the crowds of the, uh, peaceful protesters. Most of the trouble was caused by police telling people not to do things and then the people doing those things to antagonize the police (not a great idea when they have riot shields and riot batons).
Pretty much what we have here in the G20 is a confluence of assholes from all over the place and from all economic backgrounds doing various dickheads things because most people are jerkoffs
edit: I live in the city and while I am smart enough to figure out what they're protesting I honestly have no idea what the protesters are actually protesting (like, specifically) because 100% of the media coverage I have seen has been about a) cops arresting people or b) rioters doing shit. Thanks again mass media
edit2: I also don't care enough to do any sort of research due to a rare brain condition
