Have you ever heard of pressure points? I know for a fact you're not gonna be feelin well if I hit you in the diaphragm, behind the shoulder blades, in the temples, behind the knee, your shoulder joint from the front, or behind the jaw. It's far easier to disable someone than beat the shit outta them, which is what most forms of martial arts are for. If you're coming at me with a bat like a madman and I get in close and get you in the wrist, I guarantee that you won't be holding that bat for long. Now who's in trouble, the dude who was just disarmed then put in the sleeper hold, or the dude who defended himself. Let's take that same scenario, but I'm some fuck who has no martial arts training, no agility or strength whatsoever, but I have a gun, and some fuck comes at me with a bat, so I blow his brains out, now who's in trouble?
