I can’t imagine many places outside the big urban centers where you wouldn’t see folks banding together to protect their neighborhood.
It’s funny, when I spent some time in SE Asia it was common to see the neighborhood guys doing the same thing, but with clubs not firearms. If they caught the perps they’d hold them until the police showed up. Sometimes that meant hogtying them with bailing wire from 2:00AM until 9:00AM; sometimes a ritual humiliation beating by the entire block (15 or 20 people including grandmas with little sticks); and once in a while a serious public smackdown by a few of the tougher guys. The message was “Don’t ever come back here again, and tell your friends.”
Once after about an hour of village justice, the police showed up to take charge of the perp (caught red-handed with a stolen TV). The first cop walks up to the guy, stares him down for a moment, and then coldcocks him with a very serious upper right. Then they dragged him away for a certain sentence to the work farm.
Justice is much simpler and PC-free in that part of the world.
Wait till the lawyers arrive or the equivalent of the aclu.
