What, specifically, has Giuliani said about taking away people's guns? I really don't know, because it's not a big concern of mine. You can probably link me to a lot of things, because it seems to be a big concern of yours. Thanks.
I do not think the government should cut off the right to bear arms. My position for many years has been that just as a motorist must have a license, a gun owner should be required to have one as well. Anyone wanting to own a gun should have to pass a written exam that shows that they know how to use a gun, that they’re intelligent enough and responsible enough to handle a gun. Should both handgun and rifle owners be licensed...we’re talking about all dangerous weapons.

Note he is not talking about testing for a Concealed Carry permit like some states have already, but a written test to be able to buy a gun which is extreme. Once a test is required, it can then be made as difficult as any future anti-gun adminstration wants, effectively banning guns without needing to pass a law.
