Against my better judgement I just watched the video, and I'm sorry, lack of facts or not, I would not let that assailant back on my plane. He punched repeatedly, violently and rapidly. And over what? A verbal argument? (This is where the lack of facts comes in, I suppose.)

I'm by no means a "tough guy" but there's no way I'd let that guy back on if I knew at the time that's what he did. And the fact that there is blood on the seats is good enough for me, "All the facts" or not.
