I see your point here. The only solution I see is for someone to sue the state or the fedguv on a gun violation for deprivation of rights. No one would argue that the right to life is not an unalienable right. Whether I choose to use a gun or or a knife or a baseball bat is my business. At my age and physical condition, I would choose a fully automatic pistol, and would probably choose to coneal it as to not freak out everyone when I go to the bank or the deli.
Oh, that's been done. Recently we've had Silveira v Lockyer (a state case) and US v Emerson (a federal case).
The USSC refused to hear either case.
