Really? In my personal experience of the time a bunch of kids tried to steal a bike from south polo (a story I will dine out on as often as possible) running at them and shouting was pretty successful at getting a bike they tried to steal back. As flavour flav would say 'bumrush the show'.
There have been other times I've had attempted muggings (mostly as a student) and every time i've resisted, the muggers have got nothing. Plus I've got a great story from each one that makes me sound like a hero when really I'm just obstinate and perhaps not very good at judging danger.
Do that to the wrong person and you'll end up in trouble...
