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)

Update:  Dana Loesch is spearheading the effort to identify this guy with a reward, and Professor Reynolds has pledged $1000.

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.
