fergie, you don't understand the American legal system.

1) People already are sent to jail or prison for illegal possession of a firearm. Felons are not allowed to own nor possess them. I suppose we could create mandatory minimum sentences of ten years or so for each violation.

2) You can't disband a private organization. In the US Constitution we have something called "freedom of assembly." That means groups of like-minded individuals are allowed to meet unless it's a criminal conspiracy. You can't make the NRA do what you want.

3) Something else to think about: the NRA, which you clearly don't like, has a membership of almost all law-abiding members (I can't say all for statistical reasons). The people who are breaking the law, killing people with guns, are not NRA members. (For the record, I'm not a member of any gun organization.)
