In a per curiam opinion, the Court held that, although stun guns are unusual in nature and were not common during the enactment of the Second Amendment, they are included in the Second Amendment’s protections. To hold otherwise would be inconsistent with the Supreme Court’s decision in District of Columbia v. Heller, which held that Second Amendment protections extend to arms that were not in existence at the time of the founding.

Justice Samuel A. Alito, Jr. filed a concurring opinion in which he reiterated the importance of access to self-defense and the rights afforded by the Second Amendment. Justice Clarence Thomas joined in the concurring opinion.
