No, banning weapons is not the answer at all. When you make weaponry illegal all you do is make so all the gun out there are in criminal hands. If we truly lived in a society of easy access weaponry the Headline today would be. "Heavily Armed Lunatic gunned down by Intended Victims" the Death toll would be low single digits.
It’s truly amazing and quite bizarre how so many Americans can believe in such a blatantly stupid and nonsensical notion. The experience of just about every other country on Earth argues against this preposterous idea, yet somehow you all manage to hold on to it with the bone-headed determination of a captain going down with the ship.
