Unmmm I don't know, as Jessup's point is argued between real military folks all the time, I've witnessed this in real time. Try it, go to the VA and ask veterans "Was Col. Jessup right?" and watch how they respond. Because how far is too far when it comes to defending the nation, or a society, from internal or external threats? In order to be effective, do the police need to be just as ruthless as the crooks they protect society from? If the barbarians at the gates have no morals, no conscience, and will give no quarter, how do you combat that with people not willing to match that level of aggression?
