Well, I live in Ottawa where the G20 had their summit last month (or was it October... anyways). And to say that anarchists believe that all governments rest on violence to control their subjects is kind of a hipocritacle statement. I saw some of the stuff that went on, and while I was around, most of the violence originated in the anarchists provoquing police. Though, I'm pretty sure those weren't "true" anarchists, but rather young punks who don't even know what anarchy really is, they just see it as a lack of rules and laws, and of authority.
