The person in this video, whose (mug) shot is below, is seen on the now-famous video throwing punches at Steven Crowder.
How long before he is identified? And will he be prosecuted?
Language Warning for video:
(added) This video shows the attack from a reverse angle and gives an even better sense that this was an out of control mob, not an isolated person who lost his cool. (again, lanuage warning)
In the comments there are links to other blogs which identify the person. Just be careful, any identification needs to be verified not just based on Tweets or so forth.
