There is no excuse for his behavior. For example, it's one thing to pick-up a rifle and go to the defense of your fellow soldiers. But it's quite another story when they murder, rape, pillage & plunder and then claim they were only trying to help break up what was going on when they got egged on. Regardless, tonight Michigan and Ohio State battle it out on the ice (Hockey).
Fwiw, I never said his actions walking out of the stadium was acceptable.
