Here's a caption that appears with the video on Liveleak. I have no idea if it's authentic or not (most of them aren't)
Noticed this happening as I was leaving QuikTrip.
I am not entirely sure what the argument was over. But as I was leaving QT I heard something to the effect that the white guys almost hit the black guy as he was crossing the street.
After I stopped filming nobody was doing anything to help dude off the ground so I literally picked this dude up like he was a rag doll and carried him over to one the concrete potters that sit out front of QT's. He eventually caught his breath and moved on.
