In 1791, the U.S. adopted the Second Amendment which reads: “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 the 2008 case of District of Columbia v. Heller, the Supreme Court ruled that the Second Amendment protects an individual’s right to own a gun for personal use, unconnected with service in a militia. It also specifically stated that individuals have the right to keep a loaded gun at home for self-defense. [4] In 2010 the Supreme Court incorporated the right to apply to the states as well as the federal government in McDonald v. Chicago.
