Not hard, especially when there ie more then one person there to jump his ass, hit him over the head with anything.....At least try to save a fricken life, and not be only thinking of yourself........You would just stand there and ignore it, or watch it like it were a pay per view event?
What if you were the " victim "????????
Most of the time, in a situation like this, once the person see's he/she is out numbered, they will stop.
As I said, people suck, are selfish, and only think of themselves.
Edit to add :
I have done this......
Of course i would do anything i could, but i fail to see how getting stabbed is the best option.
