In 2000, federal and state legislation was introduced that would require safety locks on firearms as well as ban the importation of high-capacity ammunition magazines. Though laws were passed that made it a crime to buy guns for criminals and minors, there was considerable controversy over legislation pertaining to background checks at gun shows. There was concern in the gun lobby over restrictions on [[Second Amendment to the United States Constitution|Second Amendment]] rights in the United States.<ref>{{cite web |url=http://archives.cnn.com/2000/US/03/07/clinton.guns.03 |title=Clinton pushes Congress to pass new gun control legislation |access-date=March 16, 2008 |url-status=dead|archive-url=https://web.archive.org/web/20080316020955/http://archives.cnn.com/2000/US/03/07/clinton.guns.03 |archive-date=March 16, 2008}}.
