How is your Glock going to overthrow tyranny?

You'll need a tank to do that. And so will your neighbours.

So, you should be allowed to own artillery and mechanised equipment, and train in them in fields and paddocks.

On the other hand, there is no constitutional right to home defence. So hand in your guns, kids, or bury them in your backyard until the evil government comes to get you.

The conservative government in Australia imposed a 1% tax on its citizens to buy back all semi-automatic weapons, rifles and shotguns after a gun massacre in Tasmania a few years back. It caused the government's popularity to go through the roof.... no one wanted Australia to be like America.
