The old dude (con) knew the rules, that's why he said he moved because he was "afraid" after seeing the fellows knife. Bingo, brandishing and Bingo he was appearing to avoid. In the interview he called the fellow out for being a murderer violating his parole... this placed him clearly as a victim. If you look at the running confrontation he controlled all of it but I do not think he was looking for a fight, he just wanted the satisfaction of the fellow sitting down, he knew he was dealing with a fear biter. It didn't help that the girls egged him on with questionable comments but he was 50 years old (said so, and black don't crack) and he ended up back in the slammer because he was stupid, he got offended and couldn't let go. The duffer at the end of the fight clearly called himself the victim and his opponent the aggressor. He was not stupid, he just played it right and he knew how to box. Dang, Hat's off. Also, look at the interaction considering OODA. The duffer did good.
