New extended video mix of up-close and across the street:
Notice in the long shot, the Tea Partier is deliberately backing up to make room for two of the leftist goons pushing their way through. As they walk past him, he turns to his right to keep his sign facing them. At that point, the goon behind him cold-cocks him from behind and slams him into the wrought iron fence, then scurries away like a fat rat. Then notice how the Capitol Policeman courteously lets these three goons go by him, and then hold the Tea Partiers back as they try to get him to arrest that man so the victim could file charges against him.
