Even though I think you are joking, I'll play along.
1) so. cars are way more dangerous. so is water
2) there is no real need for most of what you have
3) ?
4) Profit
(non-automatic means that the bolt moves forward once [firing a single round] when you pull the trigger)
To be fair, with a machinegun one could kill 100 people in ~10 seconds. You can't really do that with a couple semi-autos; however, it is child's-play to shave a bolt causing uncontrolled (short of removing magazine) autofire on 1 trigger pull. And then there are bombs... So... A machinegun isn't much of an additional risk. Carrying one and a decent amount of ammo very far would be pretty absurd. In urban warfare/assault on innocents I think mobility precludes the use of such a thing unless it is a squad served weapon. It's best (and alone, only possible) as a defensive weapon, so why not legalize it?
I meant it quite seriously. About cars, yes, they are more dangerous. Vastly so. But as many people (particularly Americans) rush to point out in many thread, they are essential given the way North American cities are built. Water I'll give you though. I'm still looking for my DHMO ban.
Even if it's easy to turn a semi-auto into a full auto, I personally didn't know such a thing was possible, nor would I know how (although I'm sure the internet could teach me I suppose). But just because they are easy to make from other things, doesn't mean they should be sold as a package. Seems pretty easy to make a bomb out of farming supplies, or crystal meth from everyday pharmaceuticals, but you don't see (legal) sales of the finished product.
And you suggest using a full auto as a defensive weapon, but a defense against what? I couldn't reasonably see you using one to defend your house. If it's about all out military resistance, I suppose my problem goes much deeper than the specific gun bans.
And I fail to see how the existance of more dangerous weapons such as bombs would make it sensible to allow the private sale of machine guns.
They want them.
That's all that is necessary.
Glad to see someone gets it.
I want lots of Cocaine. Ergo, I should be able to have as much Cocaine as I want.
I want to have lots of money. Please legalize the robbing of banks.
Doesn't work like that, and you know it.
