“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.”
Such language has created considerable debate regarding the Amendment's intended scope.
On the one hand, some believe that the Amendment's phrase “the right of the people to keep and bear Arms” creates an individual constitutional right for citizens of the United States. Under this “individual right theory,” the United States Constitution restricts legislative bodies from prohibiting firearm possession, or at the very least, the Amendment renders prohibitory and restrictive regulation presumptively unconstitutional.
On the other hand, some scholars point to the prefatory language “a well regulated Militia” to argue that the Framers intended only to restrict Congress from legislating away a state's right to self-defense. Scholars have come to call this theory “the collective rights theory.” A collective rights theory of the Second Amendment asserts that citizens do not have an individual right to possess guns and that local, state, and federal legislative bodies therefore possess the authority to regulate firearms without implicating a constitutional right.
Second Amendment History
The Second Amendment (Amendment II) to the United States Constitution protects the right of the people to keep and bear arms and was adopted on December 15, 1791, as part of the first ten amendments contained in the Bill of Rights. The Supreme Court of the United States has ruled that the right belongs to individuals for self defense, while also ruling that the right is not unlimited and does not prohibit all regulation of either firearms or similar devices. State and local governments are limited to the same extent as the federal government from infringing this right, per the incorporation of the Bill of Rights.
The Second Amendment was based partially on the right to keep and bear arms in English common law and was influenced by the English Bill of Rights of 1689. Sir William Blackstone described this right as an auxiliary right, supporting the natural rights of self-defense and resistance to oppression, and the civic duty to act in concert in defense of the state.
While both James Monroe and John Adams supported the Constitution being ratified, its most influential framer was James Madison. In Federalist No. 46, Madison wrote how a federal army could be kept in check by state militias, “a standing army … would be opposed [by] a militia.” He argued that state militias “would be able to repel the danger” of a federal army, “It may well be doubted, whether a militia thus circumstanced could ever be conquered by such a proportion of regular troops.” He confidently contrasted the federal government of the United States to the European kingdoms, which he contemptuously described as “afraid to trust the people with arms.” He assured his fellow citizens that they need never fear their government because “besides the advantage of being armed, which the Americans possess over the people of almost every other nation, the existence of subordinate governments, to which the people are attached, and by which the militia officers are appointed, forms a barrier against the enterprises of ambition”.
By January 1788, Delaware, Pennsylvania, New Jersey, Georgia and Connecticut ratified the Constitution without insisting upon amendments. Several specific amendments were proposed, but were not adopted at the time the Constitution was ratified. For example, the Pennsylvania convention debated fifteen amendments, one of which concerned the right of the people to be armed, another with the 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 amendments to assure ratification.
In United States v. Cruikshank (1876), the Supreme Court of the United States 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” and thus limited the scope of the Second Amendment's protections to the federal government.
In 1939 the U.S. Supreme Court considered the matter in United States v. Miller. 307 U.S. 174. The Court adopted a collective rights approach in this case, determining that Congress could regulate a sawed-off shotgun that had moved in interstate commerce under the National Firearms Act of 1934 because the evidence did not suggest that the shotgun “has some reasonable relationship to the preservation or efficiency of a well regulated milita . . . .” The Court then explained that the Framers included the Second Amendment to ensure the effectiveness of the military.
This precedent stood for nearly 70 years, when in 2008 the U.S. Supreme Court revisited the issue in the case of District of Columbia v. Heller (07-290). The plaintiff in Heller challenged the constitutionality of the Washington D.C. handgun ban, a statute that had stood for 32 years. Many considered the statute the most stringent in the nation. In a 5-4 decision, the Court, meticulously detailing the history and tradition of the Second Amendment at the time of the Constitutional Convention, proclaimed that the Second Amendment established an individual right for U.S. citizens to possess firearms and struck down the D.C. handgun ban as a violation of that right. The majority carved out Miller as an exception to the general rule that Americans may possess firearms, claiming that law-abiding citizens cannot use sawed-off shotguns for any law-abiding purpose. Similarly, the Court in its dicta found regulations of similar weaponry that cannot be used for law-abiding purposes as laws that would not implicate the Second Amendment. Further, the Court suggested that the United States Constitution would not disallow regulations prohibiting criminals and the mentally ill from firearm possession.
Thus, the Supreme Court revitalized the Second Amendment argument.
