Individuals and groups face a deadline today to submit amicus briefs to the Supreme Court supporting firearm bans labeled assault weapons in Cook County, Illinois, and Connecticut. A filing from CRIME, standing for Citizens' Response to Increased Muzzle Energy, proposes that courts allow such bans using a formula named Measure of Muzzle Energy per Minute. That figure multiplies energy per shot at the muzzle by the number of rounds fired each minute, with the group asserting that higher results indicate greater lethality and that AR-15s along with many other semiautomatic long guns fall outside Second Amendment protection. The brief states that matching the 85,219 foot-pounds per minute from an M1 Garand shooting 30 rounds would require eight people emptying six-shot .44 Magnum revolvers three times within one minute.
