Update: linked by BreitbartTV and The Lonely Conservative, thanks!
Update #2: A geographical clue - the thug may be from the Bay Area. Via John C. Drew: "... This video was shot on the campus of Canada Community College on July 15, 2010. The CNA had just completed another rally in front of Meg Whitman's home in nearby Atherton, CA."
Update #3: His name is Mike and he is a community organizer.
Update #4: Identified! His name is Mike Griffing.
Do you recognize the man pictured below with the gray goatee and glasses wearing a CNA tee-shirt?
If you know who he is, send me the info. He assaulted/harassed Whitman volunteers at a rally this week, all captured on the video below. You can see him using his left hand to knock a camera out of one of the volunteers hands at 8 seconds and again at 12 seconds. He returns later and shoves or hits the cameraman several more times.
Here is the video:
He is wearing a red CNA t-shirt that is starting to fade -- maybe because he has worn it to multiple CNA protests. It shouldn't be hard to ID the guy.
