The Uvalde massacre is a reminder that guns are now the leading cause of death among American children.
From Justice Scalia's majority opinion in DC v. Heller:
Like most rights, the right secured by the SecondAmendment is not unlimited. From Blackstone through the 19th-century cases, commentators and courts routinely explained that the right was not a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose. See, e.g., Sheldon, in 5 Blume 346; Rawle 123; Pomeroy 152–153; Abbott 333. For example, the majority of the 19th-century courts to consider the question held that prohibitions on carrying concealed weapons were lawful under the Second Amendment or state analogues. See, e.g., State v. Chandler, 5 La. Ann., at 489–490; Nunn v. State, 1 Ga., at 251; see generally 2 Kent *340, n. 2; The American Students’ Blackstone 84, n. 11 (G. Chase ed. 1884). Although we do not undertake an exhaustive historical analysis today of the full scope of the Second Amendment, nothing in our opinion should be taken to cast doubt on longstanding prohibitions on the possession of firearms by felons and the mentally ill, or laws forbidding the carrying of firearms in sensitive places such as schools and government buildings, or laws imposing conditions and qualifications on the commercial sale of arms.26
We also recognize another important limitation on the right to keep and carry arms. Miller said, as we have explained, that the sorts of weapons protected were those “in common use at the time.” 307 U. S., at 179. We think that limitation is fairly supported by the historical tradition of prohibiting the carrying of “dangerous and unusual weapons.” See 4 Blackstone 148–149 (1769); 3 B. Wilson, Works of the Honourable James Wilson 79 (1804); J. Dunlap, The New-York Justice 8 (1815); C. Humphreys, A Compendium of the Common Law in Force in Kentucky 482 (1822); 1 W. Russell, A Treatise on Crimes and Indictable Misdemeanors 271–272 (1831); H. Stephen, Summary of the Criminal Law 48 (1840); E. Lewis, An Abridgment of the Criminal Law of the United States 64 (1847); F. Wharton, A Treatise on the Criminal Law of the United States 726 (1852). See also State v. Langford, 10 N. C. 381, 383–384 (1824); O’Neill v. State, 16 Ala. 65, 67 (1849); English v. State, 35 Tex. 473, 476 (1871); State v. Lanier, 71 N. C. 288, 289 (1874).
