That was probably a joke but the reality is that one of the first and most fun things that most prepared men would be looking to accomplish in a community spirit would be to eliminate the sociopath riff raff from the equation.
The last thing that I would want to be in a dire survival situation is an unstable sociopath with a gun that was looting and a deadly threat to every father's family.
Look at the aftermath of hurricanes, those guys are enjoying their protective role as they gather to protect their neighbors and they are looking for an excuse to act.
Until someone with a rifle and scope eliminated from a distance the threat to their family.
Maybe you were joking...
