Do Martial Art people still have to register their hands upon becoming Black Belts?

There is not/nor has there ever been a law where you have to register your hands as lethal weapons. I don't know where this belief comes from, I guess it was just a joke that caught momentum and people started taking it seriously. The same rules apply to everyone. You cannot assault another human being unless you are defending yourself from physical harm. No warning needed, if someone attacks you then you can subdue them. And someone who knows martial arts is less likely to kill someone, because they have the skills to break someone's bones and subdue them. Where as someone like me would just smash something hard on their skull, which is much more likely to kill someone than a skilled grapple.

I don't know. But I know that I have to register my big dicc as a deadly weapon.

Think this came about as a joke/comment that Ed Parker made about someone registering their hands as lethal weapons, than has some how gone on to become urban folklore lol.

Lol no.

Plus most black belts would not qualify as weapons of any sorts let alone "deadly weapons".

I have heard of that myth though.

This is not a thing and never has been.

No since black belts are given out like participation trophies and they don't mean anything any more. Maybe 30 years ago when training was real and there weren't 100 McDojos within walking distance.

I've seen 12 year olds get black belts. There's no way a 12 year can have enough training to really be recognized for the training and effort required. It's a participation trophy.

Never heard of this. With all of the martial arts out there with all the different governing bodies and ranking systems (many of which don't even use the belt system), I really don't see how this could be made law.

Did you ever think that the "guy you knew in high school" was a complete bullshitter, and was boasting unnecessarily about his skills to get out of fights?
