[Rain Man]

I agree with most of the previous posts. The fact that the crowd was yelling against the young guy, and the fact that he said something like, "I'm yelling between points" indicates that he was likely being foul and annoying. However, if he was foul and annoying enough to be thrown out, he should have been reported to security. This is completely on the woman and the old man for assaulting the guy, and they're the ones who should be arrested.
