"The white man, that landed here; He came with two great weapons. One is the bible and the other was the gun. If he didn't humble you with the bible, he'd crumble you with the gun. And he's still praising the lord and passing the ammunition." - Lewis H. Michaux
In the USA only about 15% of the children grow up completely without violence at home or at school. In Europe it's about two thirds as a rule, in Scandinavian countries over 80-90%.
Well, to follow the logic of the NRA, there would be much less violence if these poor children were all armed and could defend themselves ...
Some people in Iowa were already gearing up to do this kind of thing last week before the massacre, in response to a different event. There were two girls abducted last summer whose bodies were just found. A state GOP Senator says he is going to introduce legislation to reinstate the death penalty when the session starts in January because ... well, something. Iowa got rid of capital punishment in 1965 -- 47 years ago. These people never quit or go away.
I doubt the shooter (who killed himself!) would have been dissuaded by the threat of a death penalty.
Also, if the right to bear arms to so important, why shouldn't it extend to Palestine and Iran?
