Tribalweapon, I'm pretty sure that is just an "urban myth" if you know what I mean. It seems very unlikely. Go to a public library and do some research. Find out if that is really the law in your state. I would be interested in learning the result.
I recently had to assist in a black belt test(got my butt kicked) and the guy testing had to be registered. He had to get a picture ID saying that he was a black belt and something about should an altercation occur he must notify the police immediatly and show that card when they arive.
Just my tuppenceworth here. I'm heavily involved with cqb instruction & its implimentation in high stress environments. I have to say that most people whether they're practising martial artists or not wouldn't manage to deploy a weapon in an attack, regardless of the weapon. Most people train to use the weapon, but how many train to DEPLOY the weapon? More than that how many train to deploy the weapon in less than perfect situations under induced stress? Also, things like perfume & hairspray sprayed into the face of an adrenalised, drunk or drugged attacker won't slow them down a jot. When we're working on covert carry weapons skills for guys on undercover work we drill constantly on the ability to deploy the weapon under any circumstances. If you carry a defensive weapon or teach defensive weapons work in class make sure you drill on deployment. If you can't get it out you can't use it Sorry, this isn't quite in line with the original post.
