Dear not so much Common Sense…

Your comment, “It assumes people with guns know how to use them- which is a precarious argument to hedge your bet on” is really based on nothing more than your own personal ignorance.

According the the FBI; in those states that are ‘Shall Issue’ for Concealed Carry permits…

Police Officers shoot the wrong person 11 times more often than Civilian holders of CCW permits.

Civilian holders of CCW permits use a Firearm to PREVENT a crime 16 times as often as Criminals Commit a crime with a Firearm.

I suggest you try reading “More Guns, Less Crime” by John Lott. You might learn something.
