Americans have no Second Amendment right to carry concealed guns in public, a federal appeals court in California ruled on Thursday in a significant blow to gun-rights activists and gun owners in a large swath of the Western U.S. The San Francisco-based Ninth U.S. Circuit Court of Appeals, in a 7-4 ruling, upheld a California law requiring residents to show ?good cause? for carrying a concealed handgun. Under the California law, personal safety alone doesn’t qualify as good cause, which is defined by county sheriffs. The plaintiffs, gun owners seeking licenses to carry their weapons concealed, said the policies in San Diego and Yolo counties where they live violated their Second Amendment rights.
