Is it true, as a recent chain e-mail suggested, that the U.S. government's signing of a U.N. treaty on conventional arms will make U.S. citizens subject to gun laws created by foreign governments? No, says the Times' "PolitiFact" blog. However, it is possible that the Supreme Court might one day use an international gun control standard as a piece of evidence when writing a majority opinion on the Second Amendment. "Over the really long term, do (gun-rights advocates) have something to worry about? The answer is absolutely yes," said Peter Spiro of Temple's Beasley School of Law. "It's smart for the NRA to be mobilized on an international level."
