This will be an atrocity. There are so many things that could be done to assure that this never happens again. But if there is mention of gun laws or anything to do with guns the NRA says NO.
They don't represent the majority of gun owners anymore. They respresent the manufactorers. Sooner or later, the NO, is going to start costing them memberships.
Hopefully, but they tend to be a brainwashed bunch.
I use to have dinner at a bar after work and quite often one of the higher ups in the NRA would have dinner there too. He was a nice enough guy and he would mention to the bartender that he had to attend a meeting somewhere shortly in the future. Occasionally, he would talk about the NRA, so I asked him if he knew of court decisions that caused things to change. I never studied the case law and was just curious. I couldn't get an answer out of him. On another occasion when he was talking about the NRA, I asked since the Constitution says arms and not guns, where do you draw the line? I had to futher explain between a knife and a hydrogen bomb, what weapons should people be allowed to have and not have? The only thing I remember getting out of him was people shouldn't have nuclear weapons.
These people are taught to believe in something and not really think it through. They believe the government is screwing them of their liberties and if everybody had a gun, crime would disappear. That's possible after everybody kills each other off.
I don't know about the whole membership of the NRA, but the ones that really believe in it aren't the types to easily change or leave the organization. They view any restriction on guns is an infringement of their sacred rights and liberties.
Interesting -- did he elaborate on why people should not have nuclear weapons and why the Second Amendment would not apply? That might be a useful distinction as a starting point.
