The suggestion of the poster who says we should turn them in for the good of society infers that we are to volunteer to assume the financial loss inasmuch as he does not suggest that the government buy them back... good luck with that one.
Volunteering to give up guns is completely unnecessary in the face of the state's SOVEREIGN WILL. And the state's sovereign will is manifested through its laws and the armed forces it controls to ensure compliance with the laws.
Now, if you are suggesting that you stand a chance against that, then you probably need more luck than I do.
