I checked out a few more of the links. I stumbled onto an audio recording of the guy who got punched essentially saying (paraphrasing here) we were both in the wrong, but I totally instigated the punch and I shouldn't have.
I don't think he'd be talking like that if he had sued or planned to.
I believe Buzz titled a chapter in his new book, "The Punch Heard Round the World" about this incident. If you just google that term I'm sure you could find a ton of info on it. If you have the time/desire of course.
