In the United States, access to guns is controlled by law under a number of federal statutes. These laws regulate the manufacture, trade, possession, transfer, record keeping, transport, and destruction of firearms, ammunition, and firearms accessories. They are enforced by state agencies and the federal Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). In addition to federal gun laws, all state governments and some local governments have their own laws that regulate firearms.
