Pete Wentz Channels Ali

Several reports have surfaced about Pete Wentz punching out a heckler at an acoustic after party. The reports say that Pete ultimately got the guy knocked out with the help of random people getting their kicks in leaving the supposed victim bloodied on the floor as Pete left with his band mates.
But as we all know, there are two sides to every story. Pete says that it was true that he and the band were getting heckled but he brushed it off. However, the only way out of the place was to pass by the guy. Pete went for the diplomatic route and tried to avoid confrontation by bowing his head down but the guy grabbed him while spitting out some expletives and Pete let out a punch in defense.
He goes on to say that he’s not worried about whatever may come from it because several independent witnesses have spoken about the guy grabbing him first.
Self-defense or a great need for anger management? You be the judge.
