You're assuming too much when you assume that a bystander will attack you. So many people saw the random attacker assault Kristen, no one did a thing about it. You will be the 1 in 100 that would do something about it, chances are there will be no one else.

I know this is 2 days old and I don't want to beat a dead horse but check out this video: http://www.youtube.com/watch?v=u3PgH86OyEM

I know it is Man -> Women and Women -> Man but I think it neatly illustrates my point. And I think we can assume:

* 2 women fighting -> Public doesn't care

* women fighting man -> Public doesn't care

* man fighting women -> Public cares and will get involved

Two women fighting != a man kicking a women in the head

I think you are assuming too much when you assume a bystander won't attack a man attacking a women in public.
