Have a gun. That has always been the first rule!
Then learn the other rules:
Shooting Advice from various Concealed Carry Instructors:
A: Guns have only two enemies: rust and politicians.
B: It is always better to be judged by 12 than carried by 6.
C: Cops carry guns to protect themselves, not you.
D: Never let someone or something that threatens you get inside arm’s length.
E: Never say “I’ve got a gun.” If you need to use deadly force, the first sound they hear should be the safety clicking off.
F: The average response time of a 911 call is 23 minutes, the response time of a .357 is 1400 feet per second.
G: The most important rule in a gunfight is: Always win – cheat if necessary.
H: Make your attacker advance through a wall of bullets . . . You may get killed with your own gun, but he’ll have to beat you to death with it, cause it’ll be empty.
I: If you’re in a gun fight: If you’re not shooting, you should be loading. If you’re not loading, you should be moving, If you’re not moving, you’re dead.
J: In a life and death situation, do something. . . It may be wrong, but do something!
K: If you carry a gun, people call you paranoid. Nonsense! If you have a gun, what do you have to be paranoid about?
L: You can say ‘stop’ or ‘alto’ or any other word, but a large bore muzzle pointed at someone’s head is pretty much a universal language.
M: You cannot save the planet, but you may be able to save yourself and your family.
“Peace is that brief glorious moment in history when everybody stands around reloading”.
