I ran into an incident like that once. Uncanny. It was three guys, but only one was doing the beating. The other two were just watching and laughing. I pulled up to stop it and the three guys fled... (I think they were shocked I challenged them, even after the beater tried to insinuate he had a firearm, I just kept walking towards them, like I REALLY had one, and was not scared at all... allthough I was recooperating from a broken foot..... and had no idea what I was going to do once I got in swinging range.... I guess I was lucky my bluff worked)
Well... that's my story.
