A: There’s nothing wrong with it, but you should never practice it. If you listen to me, I would say that the best karate is to not go out at night. And not to ever dream of using it. Because if you’ll try to use it, you’ll discover that the bums know it just as well as you. And they’re often bigger than you.
And therefore, the biggest hero is the fellow who is helpless and knows to avoid trouble. The skinny helpless fellow who doesn’t know karate, he is the one who avoids trouble. It’s always like that. Who drowns? The man who knows how to swim! If you don’t know how to swim, you stay on the shore and you keep out of danger.
So although it could be that it’s not a bad idea, but I disapprove of going out with weapons at night, even with just a stick. I don’t approve of that. Because, first of all, the stick gives you a sense of false confidence, and then you’re liable to walk down a dark or dangerous street that you would have avoided otherwise. And secondly, the bum can grab the stick and use it better than you.
Therefore, the best defense is to stay out of trouble. When you’re walking down the street, and you see a few bums, or even one bum, walking towards you, even if you’re not sure if it means trouble, just cross the street. Just cross over to the other side! You’ll be surprised how lazy bums are.
