Re: "Yes. BECAUSE of the police, which can be turned against the population"
I would like to see what would happen if someone should start to buy second hand tanks and cannons.
Fun fact, you can if you've got enough money. A lot of organizations will buy them as decorations. About 45 miles from where I'm at someone set up one of the Davy Crockett nuclear cannons that they'd bought second hand as part of a military memorial. Mind you they're disabled, but I'd imagine a semi-competent gunsmith could probably fix them (maybe not THAT one....there's a bit more to it than most guns).
