RE: If they are too dangerous to own a gun,
They may be too dangerous to own a gun, but they have the right to own a gun.
You wouldn't want to take away their rights would you? If someone takes their rights away, next someone will take away your rights.
It's not a privilege...it's a right....purchasing a weapon? People won't have to pay for a criminal background checks, There will be no criminal background check, why check when criminals can have weapons. You're a criminal?...it doesn't matter...here's your gun. It's your right.
