I didn't think he was beat that bad. He was still standing at the end of the video it could have been much much worse. Hopefully this was a object lesson for him. What he did wrong in my opinion was after the first blow was throwed he tried to retreat. It was too late at that point. He should have taken the fight to the assailent. It's hard as hell to win a fist fight backing up. Plus it's really hard to hit your target with your back to it.
