Police were clearing out the Occupy DC camp and asked all of the protesters to leave. The police put up signs letting the Occupy people know to get out and take their stuff. Meanwhile, one of the rabble decided that he would rather stay and tear down the police signs. The police wound up having to tase him.
After the tasing you hear him shout loudly as his friends yell at the police.
