Son, we live in a world that has walls, and those walls have to be guarded by men with guns. Who's gonna do it? You? I have a greater responsibility than you can possibly fathom. You weep, and you curse the opponents. You have that luxury. You have the luxury of not knowing what I know -- that your death, while tragic, probably saved lives; and my existence, while grotesque and incomprehensible to you, saves lives.
