The Court has held that "the Second Amendment extends, prima facie, to all instruments that constitute bearable arms, even those that were not in existence at the time of the founding," District of Columbia v. Heller,
The court offered three explanations to support its holding that the Second Amendment does not extend to stun guns. First, the court explained that stun guns are not protected because they "were not in common use at the time of the Second Amendment's enactment."
*1028
The court next asked whether stun guns are "dangerous per se at common law and unusual,"
Finally, the court used "a contemporary lens" and found "nothing in the record to suggest that [stun guns] are readily adaptable to use in the military."
For these three reasons, the explanation the Massachusetts court offered for upholding the law contradicts this Court's precedent. Consequently, the petition for a writ of certiorari and the motion for leave to proceed in forma pauperis are granted. The judgment of the Supreme Judicial Court of Massachusetts is vacated, and the case is remanded for further proceedings not inconsistent with this opinion.
It is so ordered.
Justice ALITO, with whom Justice THOMAS joins, concurring in the judgment.
After a "bad altercation" with an abusive boyfriend put her in the hospital, Jaime Caetano found herself homeless and "in fear for [her] life." Tr. 31, 38 (July 10, 2013). She obtained multiple restraining orders against her abuser, but they proved futile. So when a friend offered her a stun gun "for self-defense against [her] former boy friend,"
It is a good thing she did. One night after leaving work, Caetano found her ex-boyfriend "waiting for [her] outside." Tr. 35. He "started screaming" that she was "not gonna [expletive deleted] work at this place" any more because she "should be home with the kids" they had together.
It is settled that the Second Amendment protects an individual right to keep and bear arms that applies against both the Federal Government and the States. District of Columbia v. Heller,
Under Massachusetts law, however, Caetano's mere possession of the stun gun that may have saved her life made her a criminal. See Mass. Gen. Laws, ch. 140, § 131J (2014). When police later discovered the weapon, she was arrested, tried, and convicted. The Massachusetts Supreme Judicial Court affirmed the conviction, holding that a stun gun "is not the type of weapon that is eligible for Second Amendment protection" because it was "not in common use at the time of [the Second Amendment's] enactment."
This reasoning defies our decision in Heller, which rejected as "bordering on the frivolous" the argument "that only those arms in existence in the 18th century are protected by the Second Amendment."
I
The events leading to Caetano's prosecution occurred sometime after the confrontation between her and her ex-boyfriend. In September 2011, police officers responded to a reported shoplifting at an Ashland, Massachusetts, supermarket. The store's manager had detained a suspect, but he identified Caetano and another person in the parking lot as potential accomplices. Police approached the two and obtained Caetano's consent to search her purse. They found no evidence of shoplifting, but saw Caetano's stun gun. Caetano explained to the officers that she had acquired the weapon to defend herself against a violent ex-boyfriend.
The officers believed Caetano, but they arrested her for violating Mass. Gen. Laws, ch. 140, § 131J, "which bans entirely the possession of an electrical weapon,"
A subsequent bench trial established the following undisputed facts. The parties stipulated that Caetano possessed the stun gun and that the weapon fell within the statute's prohibition.
The Supreme Judicial Court rejected Caetano's Second Amendment claim, holding that "a stun gun is not the type of weapon that is eligible for Second Amendment protection."
II
Although the Supreme Judicial Court professed to apply Heller, each step of its analysis defied Heller 's reasoning.
A
The state court repeatedly framed the question before it as whether a particular weapon was " 'in common use at the time' of enactment of the Second Amendment."
Instead, the court seized on language, originating in United States v. Miller,
B
The Supreme Judicial Court's holding that stun guns may be banned as "dangerous and unusual weapons" fares no better. As the per curiam opinion recognizes, this is a conjunctive test: A weapon may not be banned unless it is both dangerous and unusual. Because the Court rejects the lower court's conclusion that stun guns are "unusual," it does not need to consider the lower court's conclusion that they are also "dangerous." See ante, at 1027 - 1028. But make no mistake-the decision below gravely erred on both grounds.
1
As to "dangerous," the court below held that a weapon is "dangerous per se" if it is " 'designed and constructed to produce death or great bodily harm' and 'for the purpose of bodily assault or defense.' "
Were there any doubt on this point, one need only look at the court's first example of "dangerous per se" weapons: "firearms."
2
The Supreme Judicial Court's conclusion that stun guns are "unusual" rested largely on its premise that one must ask whether a weapon was commonly used in 1789. See *1032
The court also opined that a weapon's unusualness depends on whether "it is a weapon of warfare to be used by the militia."
In any event, the Supreme Judicial Court's assumption that stun guns are unsuited for militia or military use is untenable. Section 131J allows law enforcement and correctional officers to carry stun guns and Tasers, presumably for such purposes as nonlethal crowd control. Subduing members of a mob is little different from "suppress[ing] Insurrections," a traditional role of the militia. U.S. Const., Art. I, § 8, cl. 15; see also
C
As the foregoing makes clear, the pertinent Second Amendment inquiry is whether stun guns are commonly possessed by law-abiding citizens for lawful purposes today . The Supreme Judicial Court offered only a cursory discussion of that question, noting that the " 'number of Tasers and stun guns is dwarfed by the number of firearms.' "
The more relevant statistic is that "[h]undreds of thousands of Tasers and stun guns have been sold to private citizens," who it appears may lawfully possess them in 45 States. People v. Yanna,
III
The lower court's ill treatment of Heller cannot stand. The reasoning of the Massachusetts court poses a grave threat to the fundamental right of self-defense. The Supreme Judicial Court suggested that Caetano could have simply gotten a firearm to defend herself.
Countless people may have reservations about using deadly force, whether for moral, religious, or emotional reasons-or simply out of fear of killing the wrong person. See Brief for Arming Women Against Rape & Endangerment as Amicus Curiae 4-5. "Self-defense," however, "is a basic right." McDonald,
* * *
A State's most basic responsibility is to keep its people safe. The Commonwealth of Massachusetts was either unable or unwilling to do what was necessary to protect Jaime Caetano, so she was forced to protect herself. To make matters worse, the Commonwealth chose to deploy its prosecutorial resources to prosecute and convict her of a criminal offense for arming herself with a nonlethal weapon that may well have saved her life. The Supreme Judicial Court then affirmed her conviction on the flimsiest of grounds. This Court's grudging per curiam now sends the case back to that same court. And the consequences for Caetano may prove more tragic still, as her conviction likely bars her from ever bearing arms for self-defense. See Pet. for Cert. 14.
If the fundamental right of self-defense does not protect Caetano, then the safety of all Americans is left to the mercy of state authorities who may be more concerned about disarming the people than about keeping them safe.
Notes
Specifically, the statute prohibits the possession of any "portable device or weapon from which an electrical current, impulse, wave or beam may be directed, which current, impulse, wave or beam is designed to incapacitate temporarily, injure or kill." Mass. Gen. Laws, ch. 140, § 131J (2014). The statute includes exceptions for law-enforcement officers and weapon suppliers, who may possess electrical weapons "designed to incapacitate temporarily."
Stun guns like Caetano's "are designed to stun a person with an electrical current" by running a current between two metal prongs on the device and placing the prongs in direct contact with the person.
Stun guns are plainly "bearable arms." As Heller explained, the term includes any "[w]eapo[n] of offence" or "thing that a man wears for his defence, or takes into his hands," that is "carr[ied] ... for the purpose of offensive or defensive action."
See J. Bilby, A Revolution in Arms: A History of the First Repeating Rifles 23 (2006). Samuel Colt did not patent his famous revolver until 1836.

The court below also noted that Massachusetts no longer requires a license to possess mace or pepper spray.
