Putin must be stopped. And sometimes only guns can stop guns, 01.02.2015, Timothy Garton Ash, 01.02.2015, The Guardian http://www.theguardian.com/commentisfree/2015/feb/01/putin-stopped-ukraine-military-support-russian-propaganda,

Variant: I don't care if I fall as long as someone else picks up my gun and keeps on shooting.

I Ain't Got Time To Bleed (1999)
Context: I'm all for gun control, I just define it a little differently. If you can put 2 rounds into the same hole from 25 meters, that's gun control! If you're going to own a gun, you have an obligation to know what you're doing with it. When the Constitution gave us the right to bear arms, it also made us responsible for using them properly. It's not fair of us as citizens to lean more heavily on one side of that equation than on the other.
So I support waiting periods and training requirements for gun ownership, and I like the idea that it shouldn't be incredibly easy to get guns. I support the right to carry concealed weapons, but I think people who want a concealed-weapons permit need to pass a training and safety course. The Constitution calls for a "well-regulated militia." In other words, you need to know how to use your weapon, and practice with it.
Where I draw the line is at gun registration. A law that says that everybody who owns a gun has to be on record is too easy to abuse.
