This would be freaking awesome to see. Makes me wanna get myself a Samurai helmet and bring words around while motorcycling.
Wonder if he's related to this guy (see below). Remember him? Johns Hopkins student kills apparent burglar with sword - CNN.com
Many states, including my own and Oregon have "Open Carry" laws regarding weapons. Any weapon a person legally owns can be carried in public as long as it's clearly visible. A lot of people assume it's illegal simply because some people panic at the sight of a weapon. We call those people pansies. In fact it may be illegal to conceal some weapons that it's perfectly legal to carry openly. In my state for instance, knives above a certain size are technically illegal to conceal, but legal to carry as long as they're visible. Not that it's ever enforced since everyone and their dog carries a pocket knife down here. Maybe this guy is just trying to make a statement, or he just enjoys looking badass. Though I admit it would be awesome if he were fighting crime.
This is the best anti-mugging strategy I've ever seen. If I was a crook, there's no way in h-e-double hockey sticks I'm going to mug a sword wielding Samurai on a motorcycle. In fact, if I saw this gentleman on the street I would probably throw my wallet at him while simultaneously begging him for a photo/kiss.
