Would be fun, I highly doubt could get military to fire on own citizens though. Most I know are avid gun rights advocates.
As far as guns go, the cat is already out of the bag. Make them illegal and the same thing will happen when they tried to make alcohol illegal. As long as the Hierarchy keeps pushing Doom and Gloom on the citizens of the world, guns will always be in the hands of basically anyone who wants one. It would be wild to see the kind of guns that would be made by the underground if "they" were ever to make them illegal.
A far better argument than that armed militia nonsense. If I lived in the US, assuming I couldn't make all the guns disappear with a snap of the fingers, I'd own a gun too. It is too late.
I've had it for about 12 years and might have uses it 5 times but its worth it. Think of it as keeping an attorney on retainer.....you never know when you will need him.
