I doubt the powers to be could afford it...unless a gun buy back tax levy was to be added to the standard income tax rate...if so...then the levy should be paid for by all the non gun owners...it seems a bit rich for gun owners to pay for a levy to reimburse themselves via the IRS for their own disarmament.
Oh they aren't going to offer fair market value. Trust me. And all of the money the government has comes from either We the people or the firearm/drug trade. They'll just sell the guns the idiots turn in, for a profit by selling to the drug cartels if you believe in the conspiracy nonsense.
Mine are priceless. If they have the potential to save me, my family or someone else.. and life is priceless, then I reiterate: Mine are priceless and you can't have them. UNCONSTITUTIONAL HORSE SHIT!
I say "off with their heads" old school guillotine style. I hate to say this, but just like when Ted Kennedy kicked it, there will be another party when Feinstein kicks it.
