Okay, lemme repeat that it is NOT my argument that knives, sticks, canes, swords, machete, etc. are not used in self-defense or by criminals against guns (being used in self-defense or an attacker). Art hit it on the head, when he describes it as a Showdown... that's where I doubt the usefulness of this experiment.
Most of the examples being cited would better be served by an experiment using simunitions and bokken in a kill house, open space, etc. Quite a bit different than two drawing for the camera, or even against each other with a third party shouting "DRAW!"
Art, I live in the Republic of New Jersey where CCW is a rare as hen's teeth, I'm also a bigger collector of knives than firearms- but I can honestly say that the police here get excited enough over a pocket knife that you might as well have a so-called "assault rifle" strapped to your back. I'm a big guy that doesn't need a 3 inch piece of steel to harm or hurt anyone, but somehow that makes me dramatically more dangerous in their eyes. Um, sorry... rant mode off.
