A symbol of the Confederate flag was on the car that police say Dylann Roof, 21, drove to Charleston's historic Emanuel A.M.E. Church Wednesday, before opening fire on those gathered for a Bible study meeting. A photo of Roof on social media shows him wearing symbols of the flags of apartheid-era South Africa and white-ruled Rhodesia.

"The flag has to come down," NAACP President Cornell Brooks told a crowd gathered for a midday news conference Friday.

Calling Wednesday's killing of nine black church members in Charleston, S.C., a hate crime, the head of the NAACP says it's not appropriate for South Carolina to keep flying the Confederate flag at its state house.
