1) Rights are something that the government gives you. Stop kidding yourself. Do you have the right to smoke anywhere you wish? Do you have the right to posess an RPG launcher? Does farmer Joe need a Bushmaster .223 slung across his back while watering his Romaine lettuce crop to protect himself and his crops from a warren of hungry bunny rabbits?
2) See number 1. Can hunters hunt with land mines, bazookas, or flamethrowers?
3) Stop with the "tyrannical government" nonsense. Save it for your manifesto.
The 1994 Assault Weapon ban only prevented the manufacture or illegal import of assault weapons. It did not make it illegal to own or sell a pre-existing weapon covered by the ban. So it did not remove any weapons off the street.
In short, it was a half-assed implementation, which is why it made little to no impact.
Bring the ban back, but without the grandfather clause. Lets see what happens.
