I just heard on the radio ( a local show )that in the state of Michigan, if a person is fully trained in martial arts, that person has to regester them-selves with the state. Is this true or is this just B.S.?

Not totally sure, but I think I remember a Tae Kwon Do instructor telling me that upon achieving a certain rank you had to get registered.  Telling some dude in a bar that your hands are registered weapons is a great prelude to having your ass kicked.

I'd say BS. Been it the arts for many years, no plenty of 1-5th degree black belts(after the first, You are judged on Your students) and have never known this to be true.

I do agree with JackBurton. One of the surest ways to tell a "Poser" is for them to tell You how "Badass" they are. "If He's bad, He don't need to tell You he is. He just is."
Kinda' the whole "I'm a Badass Navy Seal" thing, all over again.

I call bs on this one too,
I personally know plenty of black belts in variaus diciplins. None of them are registered Including myself.
