Summary
Background
A woman named Jaime Caetano, who had been threatened by an abusive ex‑boyfriend, obtained a stun gun for self‑defense. Police later found the device during a consent search and she was convicted under a Massachusetts law that broadly prohibited electrical weapons, Mass. Gen. Laws, ch. 140, § 131J. The Massachusetts Supreme Judicial Court upheld her conviction, reasoning that stun guns were not protected by the Second Amendment because they were not in common use in 1789, were “dangerous and unusual,” and were not adaptable to military use.
Reasoning
The Supreme Court reviewed whether the state court’s reasoning fit with its earlier Second Amendment decisions (Heller and McDonald). The Court said the Massachusetts court misapplied those precedents. Heller protects “bearable arms” even if they did not exist at the founding, and the “dangerous and unusual” limitation is conjunctive and does not permit categorical bans on commonly owned nonlethal arms. The relevant question is whether weapons are commonly possessed by law‑abiding citizens for lawful purposes today. Finding the state court’s explanations inconsistent with that approach, the Supreme Court set aside the state judgment and sent the case back for further proceedings consistent with this opinion.
Real world impact
The ruling signals that broad, categorical bans on stun guns are vulnerable to challenge and that people who use nonlethal self‑defense devices may be able to contest convictions. The decision is not a final ruling on every aspect of stun‑gun regulation; lower courts must now reconsider the case under the Supreme Court’s framework.
Dissents or concurrances
Justice Alito, joined by Justice Thomas, concurred in the judgment and emphasized Caetano’s facts, arguing that the ban threatened the basic right of individual self‑defense.
