I somehow do not believe 99% of Americans support political violence and injuring police officers. Somebody needs to bring these people back within the rule of law. If the organizers of Occupy Wall Street won't do it, then the police need to crack down on these mobs.
And yes, that's an accurate term. Once you stop obeying the law and turn to violence, you are a mob. The Tea Party never did that, despite the wet dreams of the media.
