Following Thursday’s 5-4 ruling by the U.S. Supreme Court in the case of District of Columbia v. Heller that the Second Amendment protects an individual civil r ight to keep and bear arms, and that a municipal gun ban violates that right, the Second Amendment Foundation (SAF) and the Illinois State Rifle Association (ISRA) filed a federal lawsuit challenging the City of Chicago’s long-standing handgun ban. The case is McDonald v. City of Chicago.
