The racially divisive Confederate battle flag flew at full-mast despite others flying at half-staff in South Carolina after the killing of nine black people in an historic African-American church in Charleston on June 17. Dylann Roof, the 21-year-old white male suspected of carrying out the Emanuel African Episcopal Methodist Church bloodbath, was one of many southern Americans who identified with the 13-star saltire in red, white and blue.
