Jesus man, thats a hell of a story... I'd probably have made sure she reported the guy to the police, but I suppose there's only so much you can do without causing yourself trouble. I mean sure we'd all like to take a swing at a guy like that, but it could end up just causing more trouble. Hopefully that incident made her realize to never go back to that guy and hopefully her friend helped her out and perhaps took her in so she could get away from that douchebag.
