What is there to lie about occupy? It's full of anarchists and anarchists do things like this. Be it the violence in the occupy protests, may day protests or the protest against Johan Mehserly, the ones causing problems are always the anarchists.
Not all anarchists are the violent, revolutionary black flag types. In fact, >90% of the anarchists that I've met have been mild mannered, friendly theorists who simply do not believe that the government should exist. Let's not pigeonhole an entire section of social theory because of destructive teenagers who, while claiming anarchism as their belief system, probably couldn't converse about it intelligently.
