I just saw Obama on CNN talking about the existence of the protesters at the summit, and how "this is the great thing about America. We have the right to protest."
Right.
These days, if you want to protest at a major event, you have to go through impossible bureaucracy to get a permit. To stand in a secluded area. They have regulations on the size of sign you may carry. No bullhorns allowed, because that disturbs the "peace." Oh, but the riot police may have their own super-bullhorns to disperse everyone. That's fine.
