Cameras are a great suggestion. When the aggitators get going everyone should stay calm and just train their cameras on them. It will drive ‘em nuts! Let everyone know to come with a camera.
But they're saying the agitators will be leftist 'plants' within the Tea Party groups. So they will try to fit in with the crowd. They'll probably be carrying pro-American signs and wearing red, white and blue. It's the left that wants to photograph these supposed "right-wingers" causing trouble.
