The Supreme Court ruled Monday that the constitutional guarantee of the “right to keep and bear arms” restricts federal, state, and local governments from prohibiting the use of firearms in their jurisdictions. In a 5-4 decision, the court struck down gun bans in Chicago and the nearby suburb of Oak Park, “the last two remaining outright bans” in the country. The Chicago ban, which prohibited city residents from having handguns in their home for any reason, has been in place since 1982. The justices indicated that less severe restrictions on gun ownership might withstand judicial scrutiny, but the Chicago Tribune reports that gun rights advocates are already preparing challenges to other, less strict laws across the country. In Chicago, lawmakers are already discussing new gun-control measures. Mayor Richard Daley told the Chicago Tribune that the City Council could consider new laws designed to protect first responders as early as Wednesday.
