Gabriel Giffords and her husband are now speaking out on gun control. The fact that she was a shooting victim will give her more press, and perhaps percieved credibility, than some of the other anti gun voices.
They do mention that both are gun owners and not against gun ownership. As i read her comments she's advocating background checks for all gun transfers and a limit on magazine capacity.
Those are both things that I can conceive happening. Not that I support them. I just think they're possible.
