Second Amendment to the United States Constitution
In McDonald v. Chicago (561 U.S. 742 (2010)), the Supreme Court said in a 5-4 decision that the city of Chicago could not make it illegal for citizens to own handguns. The Court ruled that the right of an individual to "keep and bear arms" protected by the Second Amendment is incorporated by the Due Process Clause of the Fourteenth Amendment. The court held that it applies to the states.
