Guess what? You can get a gun anywhere if you know the right people and are willing to pay enough.

Strip a gun and ship the components. Would you know a sear if you saw one? Or a trigger spring from any other spring? Or hide the entire weapon in a cargo of pipes, or inside a bag of cement. Or have a machine shop available and build it -- the plans are available. Or use one left over from one of the many wars.

As for self-defense, that's a specious argument. First, the baddies have to fire first (it's just not done to shoot someone because you think he or she might be a bad 'un). Secondly, it you're armed you're the first target. Thirdly, unless you've been in actual, blood-and-brains-on-the-ground combat you have no idea how you will react when someone is shooting at you with the intent to kill. Fourthly, the police or military will be shooting anyone who is "not one of us" who has a gun.

And you will get this thread closed if you keep using it as a mouthpiece for your views.
