Laz, the remark about "nukes don't kill people, tyrants do" was directed against the logic that "guns don't kill people, people do."
I don't think we're worried about the nukes in NK because they might accidently go off. I think we're worried they might shoot them at someone, or more importantly, give them more bargaining power from simply having them. I know it has nothing to do with the second ammendment, but I'm only talking about the logic. You cant tell the honest law abiding citizens in high crime areas, not to worry because "guns don't kill people, people do." Yes - knives kill too, and baseball bats and hammers. But its a lot easier to get caught in a crossfire of guns than it is a knife fight. And this happens a LOT in inner cities. Bullets start flying, and all of a sudden a kid playing on the sidewalk is dead, a lady driving by on the way to church is dead, and some poor guy just waiting for a bus is dead.
Then the argument comes out - well get tougher on crime! Good argument if everyone in this country was a rational thinking being. But unfortunately when some crack head is mad because he was scammed for a few rocks, chances are he is not thinking about the penalties for a gun crime, and nor is he overly worried about any unlucky bystander that happens to be in the way of his drive by.
Well why does a criminal have a gun anyway? Because he's a criminal and guns are as common as acorns. Shouldn't be hard for even a nutty squirel to get a hold of one.
