Just the way some portions of this thread read, have you not read it? lol
Honestly, while I know it is part human instinct to be drawn to something like this, and while I think the drunk dude got what was coming to him, it was a real sucker punch. While I am not really for fighting, both the drunk, and the "puncher" are both in the wrong. It's also human nature I suppose to see those who deserve it get theirs, and the world of pocket camcorders/cameras has brought daily stuff like this to the main stream, it is still a drunk getting knocked out. . .lord, just wait to see the videos after tonight, the greatest amateur night there is!
I was in a similar situation back in the mid 90's where a dude was roughing his girlfriend up, I got involved, dude started **** with me, knocked dude out, and had the book thrown at me basically because the girlfriend didn't want to press charges on the a** that was being an abusive prick to her. Seems like today, even when trying to do the right thing, you can end up in more trouble than those committing the act.
