ATLANTA — Confederate flags will continue flying at Stone Mountain Park near Atlanta because Georgia law prevents their removal, the head of a state authority that oversees the park said Wednesday. The law would have to be changed for the flags to be removed, said Bill Stephens, chief executive officer of the Stone Mountain Memorial Association. Stephens said the park's Flag Terrace, where multiple versions of Confederate flags fly, was donated by the United Daughters of the Confederacy in 1964.
