In my area a man was literally beating his girlfriend in front of a bar and someone stepped in. The girl jumped on the guy and the guy beating her hit the other man knocking him to the ground where he hit the back of his head and died. This made the local news in our area. It can cost you to involve yourself with strangers. I learned years ago some people in abusive relationships still want to be there, and the drama is part of their existence. A sad truth. Your article nailed the fact that abusive people are dangerous. I would say most of them are potential murderers.
