IT BEGAN WITH A GUN. On September 1, 1939, the German army invaded Poland. Two days later, Britain and France declared war on Germany. In the October 1939 issue of Detective Comics, Batman killed a vampire by shooting silver bullets into his heart. In the next issue, Batman fired a gun at two evil henchmen. When Whitney Ellsworth, DC's editorial director, got a first look at a draft of the next installment, Batman was shooting again. Ellsworth shook his head and said, Take the gun out.1 Batman had debuted in Detective Com-ics in May 1939, the same month that the U.S. Supreme Court issued a ruling in United States v. Miller, a landmark gun-control case. It concerned the constitutionality of the 1934 National Firearms Act and the 1938 Federal Firearms Act, which effectively banned machine guns through prohibitive taxation, and regulated handgun ownership by introducing licensing, waiting period, and permit requirements. The National Rifle Association supported the legislation (at the time, the NRA was a sportsman's organization). But gun manufacturers challenged it on the grounds that federal control of gun ownership violated the Second Amendment. FDR's solicitor general said the Second Amendment had nothing to do with an individual right to own a gun; it had to do with the common defense. The court agreed, unanimously.2
