GENEVA - The United States has 90 guns for every 100 citizens, making it the most heavily armed society in the world, a report released on Tuesday said. U.S. citizens own 270 million of the world's 875 million known firearms, according to the Small Arms Survey 2007 by the Geneva-based Graduate Institute of International Studies.

Americans have "the right to keep and bear arms"...that may have something to do with it!
