"we haven't decided what that is yet" - What a bunch of bull. They know exactly what they want to do and how they intend to do it, they're just waiting for the right time.
Bout to go completely outside the realm of political correctness.
Saving 1, 100, or even 1000 lives is no excuse for disarming the American public because those lives WILL be reclaimed 1000 fold down the line. Stripping the people of their defense opens the door to tyranny which leads to persecution and eventually genocide.
Lets ask the real question
How many lives are they willing to sacrifice to accomplish their anti gun agenda? Is one life today worth more than the lives of every citizen in the US 20 years from now?
Edit: I do realize that disarming us would not save any lives at present either.
