The District of Columbia argues that the prefatory clause declares the Amendment’s only purpose—to shield the state militias from federal encroachment—and that the operative clause, even when read in isolation, speaks solely to military affairs and guarantees a civic, rather than an individual, right. In other words, according to the District, the operative clause is not just limited by the prefatory clause, but instead both clauses share an explicitly civic character. The District claims that the Second Amendment “protects private possession of weapons only in connection with performance of civic duties as part of a well-regulated citizens militia organized for the security of a free state.” Individuals may be able to enforce the Second Amendment right, but only if the law in question “will impair their participation in common defense and law enforcement when called to serve in the militia.” But because the District reads “a well regulated Militia” to signify only the organized militias of the founding era—institutions that the District implicitly argues are no longer in existence today—invocation of the Second Amendment right is conditioned upon service in a defunct institution. Tellingly, we think, the District did not suggest what sort of law, if any, would violate the Second Amendment today—in fact, at oral argument, appellees’ counsel asserted that it would be constitutional for the District to ban all firearms outright. In short, we take the District’s position to be that the Second Amendment is a dead letter.

In determining whether the Second Amendment’s guarantee is an individual one, or some sort of collective right, the most important word is the one the drafters chose to describe the holders of the right—“the people.” That term is found in the First, Second, Fourth, Ninth, and Tenth Amendments. It has never been doubted that these provisions were designed to protect the interests of individuals against government intrusion, interference, or usurpation. We also note that the Tenth Amendment—“The powers not delegated to the United States by the Constitution, nor prohibited by it to the states, are reserved to the states respectively, or to the people”—indicates that the authors of the Bill of Rights were perfectly capable of distinguishing between “the people,” on the one hand, and “the states,” on the other. The natural reading of “the right of the people” in the Second Amendment would accord with usage elsewhere in the Bill of Rights.

When we look at the Bill of Rights as a whole, the setting of the Second Amendment reinforces its individual nature. The Bill of Rights was almost entirely a declaration of individual rights, and the Second Amendment’s inclusion therein strongly indicates that it, too, was intended to protect personal liberty. The collective right advocates ask us to imagine that the First Congress situated a sui generis states’ right among a catalogue of cherished individual liberties without comment. We believe the canon of construction known as noscitur a sociis applies here. Just as we would read an ambiguous statutory term in light of its context, we should read any supposed ambiguities in the Second Amendment in light of its context. Every other provision of the Bill of Rights, excepting the Tenth, which speaks explicitly about the allocation of governmental power, protects rights enjoyed by citizens in their individual capacity. The Second Amendment would be an inexplicable aberration if it were not read to protect individual rights as well.
