According to the poster of this clip, the man who recorded it and was attacked by the frat kids describes the incident.
"I'm a bouncer at one of the local bars. They followed me for 3 blocks trying to grab me and get my phone. Said they would kill me trying to punch and smacking me with a bag of begals etc... Once I got to the bar I went inside and everything else was taken care of. I can't really get into what happened after I went inside, but I'm fine."
