It will be a bigger problem in disarmed cities. There, any mob beats any individual or small group.
Try it in a gas station in SC, and you might get carried out feet first. Thirty round magazines, baby. The first few go down, the rest will scatter pronto.
And it won’t be repeated in that county for a generation.
