I don't think anyone in their right mind is thinking of getting guns back except for the occasionally held and rarely productive public gun buy-back program. Nor is anyone suggesting the wholesale disarmament of legal gun owners. The objective is slowing the trend going forward. Deterrence through universal background checks, the banning of high capacity mags and assault weapons and other over-the-top weaponry that no one but the military needs or murders want.

As for the woman who shot the intruder, it could have just as easily gone the other way (and I've posted a/b the time I damn near shot a plain clothes cop because I thought he was a prowler). Sorry, but IMHO, that just doesn't balance the problem.
