The right of United States citizens to keep and bear arms is primarily addressed in the Second Amendment to the U.S. Constitution. The text of the Second Amendment 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."
The amendment highlights the importance of a "well regulated Militia" for the security of a free state and establishes the individual right of the people to keep and bear arms. Interpretations of this amendment have been the subject of ongoing debate regarding gun rights and regulations in the United States.
