We have courts instead of mob justice in civilized societies for good reasons. One of those reasons is that mobs rarely follow due process. Once you create a class of people it is okay to enact mob violence against, all you need to do is start rumors to take out the anyone you don’t like. People of particular political persuasions. People of particular sexualities. People of particular races. “Oh Jim? Yeah, I heard he’s a pedo - lets run him out of town! (plus then he wont be able to open that donut shop that would have competed with mine…)”
