Alan Grayson's Latest: "Assault at the Webster Rally" (Video)

This was uploaded on Alan Grayson's YouTube page last night, it shows a Grayson supporter walking up behind Daniel Webster who is speaking at a rally. The man has an Alan Grayson sign in his hand, another man at the Webster rally sees it and rips the sign out of his hands. I found it interesting that this was caught on 2 cameras, were they trying to provoke a response so they could get it on tape? Looks like it to me...
