If you find yourself under lethal attack don't be kind. Be harsh. Be tough. Be ruthless.
An unarmed man can only flee from evil, and evil is not overcome by fleeing from it.
Remember the first rule of gunfighting ... have a gun.
The proper course of action, when under attack, is usually to counterattack.
If it is ever your misfortune to be attacked, alertness will have given you a little warning, decisiveness will have given you a proper course to pursue, and if that course is to counterattack, carry it out with everything you've got! Be indignant. Be angry. Be aggressive.
Safety is something that happens between your ears, not something you hold in your hands.
