The constitution is useless if you interpret in such a way as to destroy the country it is meant to govern.
Please tell me the date on which a rulebook became necessary. I don't believe that such a rulebook was necessary when the Bill of Rights was ratified. How do you justify imposing a rulebook without the benefit of a Constitutional amendment?
Those of us who do not fear arms in the hands of the law-abiding, and who recognize that the non-law-abiding will ignore such laws, do not see the need for such a rulebook. There is no power on earth that can disarm evil people without destroying them.
