The man to protect you is you. Not the state, not the agent of the state, and not your hired hand—YOU!
Jeff Copper in a short article, Cooper VS. Terrorism, reprinted from Guns & Ammo annual 1975, advocating everyone become their own bodyguard. That one should be armed and trained for close combat, and not depend on anyone else. It is mildly alarming prospect. In the bio of the author, Jeff Cooper, we learn that he was innovator of Modern Technique of the Pistol, practices and principals to maximize combat effectiveness.
For some more alarming thoughts here is poem that Jeff Cooper posted in his armory about shotguns. He also worked better ways of killing with shotguns along with rifle and pistol.
"The Colonel loves his twelve gauge
It hits so very hard
"That when he shoots his enemies
It tears them all apart
It blows off chunks of tissue
And leaves their clothing red
It leaves them ripped and shattered
And almost always dead
It vaporizes muscle
It pulverizes bone
Yet shotguns are the weapons
The even yuppies own
They claim they only use them
For shooting ducks and skeet
But when you're stuck, a load of buck
Turns predators to meat
