Dave Kopel on the UN matter
Dave posts on it at the Volokh Conspiracy.
"If a few hundred votes had changed in Florida in 2000, or if 60,000 votes had changed in Ohio in 2004, the results of the 2001 and 2006 U.N. gun control conferences would have been entirely different. There would now be a legally binding international treaty creating an international legal norm against civilian gun ownership, a prohibition on the transfer of firearms to "non-state actors" (such as groups resisting tyrants), and a new newspeak international human rights standard requiring restrictive licensing of gun owners. With a Presidential signature on such a treaty (even if the treaty were never brought to the Senate floor for ratification), the principles of the anti-gun treaty would be eroding the Second Amendment, through Executive Orders, and through the inclination of some courts to use unratified treaties as guidance in interpretting the U.S. Constitution."
