They won't learn from it, they willl keep saying the same thing. No pain for them, and a me first character, a macho character too, makes them immune.
It's very simple, take away assault weapons and not allow them, no one wil be killed after with them. It's so very clear, when a gun loving mother has a son who kills her and children like he did. There are lots of kids like that, often picked on by bullies, you know the kind of people, the gun nuts often are bullies as well. If you have guns in your home, the kid hiding his anger will find them and some of those kids will continue to mass murder.
There is no defense to not taking away all assault weaponry..
::If only every student had one or two guns each this never would have happened:::
How do you know if one of those students won't start a shooting spree? The problem with the NRA's premise that only a good guy with a gun can stop a bad guy with a gun, is that how do you know in advance who is good or who is bad? How do you know if the good guy won't turn ino a bad guy over some personal issue in their personal lives?
