It is not a good question. Good questions have answers yet to be known. Here, the answer is obvious: seriously enforce the ones we have and make more.
Well, an A#1 place to start is to stop selling so many new and used ones to any one who wants one and on the thinnest pretext. Tax the living crap out of ammo, make registration laws with real teeth, and quit freakin' extolling the virtue of gun ownership and all of the stupid open and hidden carry laws and, finally, convince people like you that there is a way that does not include throwing your hands in the air or clinging sadly to an old and moribund constitutional amendment.
