(The bit about schools is rather interesting, given current debate.)
It is impossible to say whether erasing the Second Amendment would bring down gun deaths in America. But this is an academic query: changes to the constitution require the unlikely assent of two-thirds majorities in the House and Senate and three-quarters of the states. The better question is whether repealing the amendment is a must for pursuing gun control. It is not. The Heller majority opinion did not, in the words of its author, the late Justice Antonin Scalia, secure an “unlimited” right to buy or carry weapons. The Second Amendment would not, for example, scuttle bans on concealed weapons or machine guns. And Justice Scalia emphasised that nothing in Heller “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”. Nearly every gun regulation under discussion today—from expanded background checks to bans on military-style weapons—would seem to pass constitutional muster.
