You see a wave of men in orange inmate suits walking down the street towards your home. They have pipes and makeshift clubs in their hands but they do not seem to be breaking into any homes or bothering anyone. At this distance you could take most of them out with your AR-10 but once they get close you will be overwhelmed if they try to jump you. Do you take the chance and let them pass or do you start shooting people who have done nothing to you.... yet? Why?
