Perhaps you can pray to the all-loving sky pixie to have the 2nd Amendment wiped off the Bill of Rights.
Or we can just interpret "Well-Regulated Militia" to mean exactly that.
You can have a gun, after you pass a rigorous background check and receive rigorous training.
Just like people in the Army and the National Guard do.
Well, at least you offered a solution based on Constitutional interpretation instead of a picture from a recent shooting to stir the emotion like I would have expected. I have to give you credit there.
Hey................the gun owners have stated repeatedly that "guns don't kill people, people kill people".
So..................here's the solution. Just like you have to have training, and pass a test in order to drive a car, you should have to get training, pass a basic firearms safety course, get mentally screened, and upon completion of that, you are issued a card (good for 4 years just like a drivers liscence), and with that card, you can buy all the guns you want.
If, for some reason, when it comes time to renew your card, if you are unable to pass the basic refresher course (like you do with drivers liscences), you don't get to keep your guns because you are no longer eligible.
Hey.................I know that I had to go through about a full week of weapons training before I was allowed to serve on the Security Force and carry a weapon while I was in the military.
