Important events regarding gun legislation occurred in the following years. In 1791, the
United States Bill of Rights were ratified, which included the
Second Amendment to the United States Constitution which stated that "A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed." In 1934, the
National Firearms Act (NFA) was signed into law under President
Franklin D. Roosevelt's Administration in an effort to curb prohibition-era violence. In fact, "...homicides continued to diminish each year for eleven years straight [after the repeal of Prohibition]." In 1938, President Franklin D. Roosevelt signed the
Federal Firearms Act of 1938 (FFA) into law, requiring that all gun-related businesses must have a
federal firearms license (FFL). In 1939, through the court case
United States v. Miller, the
Supreme Court of the United States ruled that Congress could regulate interstate selling
sawed-off shotguns through the National Firearms Act of 1934, deeming that such a weapon has no reasonable relationship with the efficiency of a well-regulated militia. In 1968, following the spree of political assassinations including: the
assassination of John F. Kennedy, the
assassination of Robert F. Kennedy, and the
assassination of Martin Luther King Jr, President
Lyndon B. Johnson, pushed Congress for the
Gun Control Act of 1968 (GCA). It repealed and replaced the FFA, regulated “destructive devices” (such as bombs, mines, grenades, and other explosives), expanded the definition of
machine gun, required the serialization of manufactured or imported guns, banned importing military-style weapons, and imposed a 21 age minimum on the purchasing of handguns from FFLs. The GCA also prohibited the selling of firearms to felons and the mentally ill. In 1986, contrary to prior gun legislation, the
Firearm Owners Protection Act (FOPA) (1986), passed under the
Ronald Reagan administration, enacted protections for gun owners. It prohibited a national registry of dealer records, limited ATF inspections to conduct annual inspections (unless multiple infractions have been observed), allowed licensed dealers to sell firearms at "gun shows" in their state, and loosened regulations on the sale and transfer of ammunition. However, the FOPA also prohibited civilian ownership or transfer of machine guns made after May 19, 1986, and redefined "
silencer" to include silencer parts. In 1993, the
Brady Handgun Violence Prevention Act, named after a White House press secretary who was disabled during the
attempted assassination of Ronald Reagan, was signed into law under the
presidency of Bill Clinton. This act required that background checks must be conducted on gun purchases and established a
criminal background check system maintained by the
FBI. In 1994, the
Violent Crime Control and Law Enforcement Act was signed into law under the
presidency of Bill Clinton, which included the
Federal Assault Weapons Ban, effectively banned the manufacturing, selling, and possession of specific military-style
assault weapons such as
AR-15 style rifles and banned
high-capacity ammunition magazines that held over 10 rounds. Banned arms that were previously legally possessed were
grandfathered. The ban expired in September 2004. In 2003, the
Tiahrt Amendment proposed by Kansas Representative,
Todd Tiahrt, limited the ATF to only release information from its firearms trace database to only law enforcement agencies or a prosecutors in connection with a criminal investigation. In 2005, The
Protection of Lawful Commerce in Arms Act was signed into law under the
presidency of George W. Bush. This act protected gun manufacturers from being named in federal or state civil suits by those who were victims of crimes involving guns made by that company. In 2008, the Supreme Court ruled in the case
District of Columbia v. Heller that the Second Amendment is an "individual right to possess a firearm unconnected with service in a militia" and struck down Washington D.C.'s handgun ban. But the Supreme Court also stated "that the right to bear arms is not unlimited and that guns and gun ownership would continue to be regulated." In 2010, the Supreme Court ruled in the case
McDonald v. Chicago that the Second Amendment is
incorporated and thus applies against the states. In 2016, the Supreme Court ruled in the case
Caetano v. Massachusetts that "the Second Amendment extends,
prima facie, to all instruments that constitute bearable arms, even those that were not in existence at the time of the founding". In 2022, the Supreme Court ruled in the case
New York State Rifle & Pistol Association, Inc. v. Bruen "that the Second and Fourteenth Amendments protect an individual’s right to carry a handgun for self-defense outside the home" and that "the
State’s
may-issue licensing regime violates the Constitution." ==Second Amendment==
