The Second Amendment is applicable to the states through the Fourteenth Amendment's Due Process Clause.
Professor Notes

In this landmark case, the Supreme Court addressed the applicability of the Second Amendment to state and local governments through the Fourteenth Amendment's Due Process Clause. The Court's 5-4 ruling emphasized the fundamental nature of the right to bear arms as a constitutionally protected right that applies to all levels of government. It reaffirmed the core holding of District of Columbia v. Heller, establishing that the Second Amendment is not merely a federal right, but one that extends to individual states, thus limiting their ability to impose stringent gun control regulations.

Professors will likely emphasize the significance of this decision in framing the current legal landscape surrounding gun rights in America. An understanding of the Court’s incorporation doctrine and how it applies to the Second Amendment is crucial for students, as it showcases how the Supreme Court interprets the relevance of constitutional rights in the states. This decision also serves as an important precedent for future cases involving the Second Amendment and state legislation on firearms.
