Idiot "bystanders"!
be careful- you dont know what the 'bystanders' saw
I walked into the midddle of a fight last month when an old guy was kicking the crap out of a couple of young punks- he had one down and I told him if he injured him any further I would testify against him as a witness- he calmed down.
it turns out the old guy was attacked by the two young punks -it was not the old guys fault (tough old guy too!!!)- I apologized for yelling at him but he agreed I had not seen the beginning and I was right that he could have hurt the kid past the point of self-defense and gotten into trouble if I hadn't stopped him...
