militia. The Massachusetts convention also ratified the Constitution with an attached list of proposed amendments. In the end, the ratification convention was so evenly divided between those for and against the Constitution that the federalists agreed to the Bill of Rights to assure ratification. In United States v. Cruikshank (1876), the Supreme Court ruled that, "The right to bear arms is not granted by the Constitution; neither is it in any manner dependent upon that instrument for its existence. The Second Amendments means no more than that it shall not be infringed by Congress, and has no other effect than to restrict the powers of the National Government." In United States v. Miller (1939), the Supreme Court ruled that the Second Amendment did not protect weapon types not having a "reasonable relationship to the preservation or efficiency of a well regulated militia". In the 21st century, the amendment has been subjected to renewed academic inquiry and judicial interest. In District of Columbia v. Heller, the Supreme Court handed down a landmark decision that held the amendment protects an individual's right to keep a gun for self-defense. This was the first time the Court had ruled that the Second Amendment guarantees an individual's right to own a gun. In McDonald v. Chicago (2010), the Supreme Court clarified that the Due Process Clause of the Fourteenth Amendment incorporated the Second Amendment against state and local governments. In Caetano v. Massachusetts (2016), the Supreme Court reiterated its earlier rulings 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" and that its protection is not limited to "only those weapons useful in warfare". The debate between various organizations regarding gun control and gun rights continues. Text There are several versions of the text of the Second Amendment, each with capitalization or punctuation differences. Differences exist between the version passed by Congress and put on display and the versions ratified by the states. These differences have been a focus of debate regarding the meaning of the amendment, particularly regarding the importance of what the courts have called the prefatory clause. The final, handwritten original of the Bill of Rights as passed by Congress, with the rest of the original prepared by scribe William Lambert, is preserved in the National Archives. This is the version ratified by Delaware
