I'm not even sure it is a knock out game. I was under the impression that was just a name that news organizations made up to grab a viewers attention. What this is, is just simple, no future, idiot males preying on people that won't fight back. Seriously, I'm sure we have met many people in our lives where we think "yeah this guy is going nowhere in life", but I can't think of a single acquaintance that I would guess is such a low life that he would assault a person without any premeditation. Scum.
