Who cares about the law - if there is a risk you could get seriously hurt then you should man-up and stop the f-wit by whatever is the best method. Make sure you show them your weapon before they get within 10 ft of you, and yell out "stop or you're gonna drop".

I live in a country where the law requires us skinny dudes to run chicken as the only form of self defense. Believe me, after 55 years of running chicken it seriously affects your self esteem and confidence.

I would concealed carry in an instant, but here you get 14 years jail time if you even own a gun. It's a bullies playground.
