Well, don't assume everyone who is Asian is a black belt, or even a martial artist at all. Some people assume everyone in Asia is a martial artist. And I doubt a burglar would dress as a martial artist would (I don't even know what he/she would look like). I'm pretty sure hands are not considered lethal weapons, but in certain cases your martial arts experience may work against you in the courts. You might want to try threatening with the gun first, and if he doesn't put his hands up, I'd say shoot him (preferably in a non-lethal spot like leg or arm) This is all assuming you would be home when the criminal breaks in (I think they usually they wait until you leave), and you are able to get your gun without him knowing you are home. Might want to reach for the phone before the gun.
