Gun rights advocates have worked for years to undo the District of Columbia's tough restrictions on firearms. A new legal victory has thrown city officials into a tailspin over the prospect of gun owners carrying weapons on the streets, says the New York Times. A federal judge struck down the decades-old ban on carrying guns in public. Yesterday, the judge put a 90-day hold on the ruling. Now officials must decide whether to appeal the decision, which gun rights advocates say they would welcome because it might lead to a Supreme Court victory, or write a new law laying out specifications for who could carry a gun and under what circumstances.
