Add this video to the list of sports fans behaving badly.  Here's footage from the parking lot of the Chargers/Cowboys game this past weekend. It starts a visibly upset Cowboys fan who gets slapped in the face by a female. Then as the fight starts to escalate, not one, but TWO people get hit over the head with beer bottles.

Throughout the entire video, is an innocent bystander who keeps jumping in the video to make sure the person shooting the footage knows he was cut by the flying glass.
