Well, if I had my cell phone with me, I may have just called 911 to report it, right in front of her for a scare at least, and to report her for the illegal chain. But I didn't have my phone and hanging around her without phoning the cops would have been perceived as threatening and then I would be on the hot seat.
Nobody else was around to see what happened so I can just see someone finally arriving on the scene, this woman lying and telling the other person that I tried to assault her, a cell call made and now I'm the one in trouble. And guess what, the cops would probably side with her because that's the way our wonderful society works.
