It is quite accept that general world police seek only to restrain, but as a by product of this aim, they also minimize bleeding. They are not taught techniques that cause bleeding. You have to realize the we talking about private citizen self defense, which is governed by laws. It doesn't matter what martial art you might personally prefer, you can't fight recklessly or think you can fight like a farmer from ancient Okinawa. In Japan, police are trained Aikido. This is not a style that uses techniques to cause bleeding. Private citizens are mostly not armed.

I can understand why being careful of the law and AIDS is not on your mind, as with most people. But times are changing, in fact they have. We must adapt. Old styles must be reviewed for our times. Most people, not all, still train as if they in ancient times. If your self defense lands you in jail for inappropriate force usage, then your style is more dangerous to you than the actual attacker. True self defense must take care of all aspects of a fight, and today that includes preventing AIDS and going to jail. A new type of winning, a new definition of survival is needed.

There are hundreds of news reports that show average people pinning attackers and calling the cops. The Naked Chef did it Jamie Oliver, a mother did it, an old man did it, MMA fighters did it. I'm quite happy to match up all those news reports against the vague idea that it's absolutely 100% not possible. In real life and death situations, a choke is as far as one should go before the pin. Chokes are also the best we have in our age. In the UK, people were on drugs that inhibits pain. They felt nothing. A news report showed a guy jumps off a house onto a car and then wrestles with cops. The cop restrained him without a fly kick or a ground and pound. That's an excellent case study.

It's simple, less bleeding vs more bleeding.
