Ask high school graduates whether the Bill of Rights governs cities and states and most of those who paid attention during civics class will answer, “Of course.” But the U.S. Supreme Court is pondering that very question. Proponents of social engineering frequently cite the Constitution as their justification for laws that intrude on personal liberties and the sovereignty of states. Yet they adopt a different stance when the nation’s basic documents of government do not support them. That seems to be the situation now, with Supreme Court justices hearing a case that involves gun control. In effect, the city of Chicago wants the court to rule that a municipal handgun ban can stay in effect there. In 2008, the court ruled against a similar ban in Washington, D.C. — meaning that Chicago wants to be exempted from the court’s interpretation of the Second Amendment. Justices should say no, of course. The Second Amendment protects all Americans.
