If you want to see the effectiveness of typical martial arts training against a really mean street fighter, I suggest you rent a couple of the “Ultimate Fighting Championship” videos. I know a guy who fought in one of them, and he is a 4th degree black belt. I think he lasted about a minute, against a big brawler.
It’s one thing to use your refined techniques in a Dojo, it’s another to be able to keep your composure when some guy is headbutting you, biting your nose, spitting in your face, etc.
I say this as someone who trained 7 days a week in Karate (Goju Ryu) for years. If you are a nice, civilized person and your assailant is a maniacal street fighter, you’ve got a big problem, especially if he has a size advantage over you.
Now, in a typical confrontation against your average drunk, it’s a different matter. But those situations are usually easily avoided. I lived in a rough part of town, and went out to rough bars (I like the Blues, and you don’t find a lot of blues bars in upscale neighborhoods), and I only ever had to use my skills once, and that ended very quickly.
Martial arts are wonderful. They teach you discipline, boost self-confidence, and give you grace and flexibility. They help you understand other cultures, and give you a different perspective on life. And, you stay in good physical condition. Martial arts can also be useful in certain self-defense situations. But you aren’t going to be able to handle everything thrown at you.
Glitch: I’ve done the gun disarming thing with squirt guns, and most people could get the gun deflected without getting wet. Mind you, we set up the experiment so that the gun holder didn’t know what was coming. There’s a big, big difference there. When measuring reaction times, the slowest part is the brain’s reaction to stimulus and the calculation of appropriate response. If the person is standing there with his finger taut on the trigger, KNOWING that the opponent is going to make a move for the gun any second, his reaction time will be much, much faster.
But this is a moot point, because I agree with pretty much everything you said about dealing with guns.
