Let me check I have 100% understood you. Is it your position is that someone with a clean record, for example Jared Laughner, should be free to get the materials to make a nuclear weapon?

Let me check if I have 100% understood you. Is it your position that someone with a clean record who is living in a free market libertarian society will be able to easily obtain those materials in secret, no questions asked, without anyone knowing about it?
Do remember that if you have the materials and an internet connection, you have all you need for a bomb. Incidentally, Jared Laughner had an internet connection. Have you now moved to the position that he was entitled to a nuke?
