Post shtf your problem neighbors will want your food. I doubt the druggie son or the wife will be willing to work in exchange for food. The father is influenced and controlled by the wife don’t expect anything good to happen with him. He’s gone along with her already on everything else. When they run out of meat from lack of success hunting, they will come begging or they will be stealing from your garden. At that moment when you catch them, you will be forced to decide what action to take.
