Complicated problems have complicated answers.

Ban all firearms? How do you propose to do it if someone won't cooperate?
Dismantle the NRA? Again, how? The First Amendment guarantees free association.
Better background checks? Great, but how do you get ever agency to cooperate? And what about entry backlogs?

Throwing money at it isn't the answer, either. We need a cultural revolution, one that returns our "gun culture" to about 1958. It's easy to pass a law, it's far, far more difficult to get it to work.
