The Department of Justice said it is investigating whether Dylan Roof's alleged attack on Emanuel African Methodist Church in Charleston was an act of domestic terrorism."This heartbreaking episode was undoubtedly designed to strike fear and terror into this community," a department spokeswoman said. "And the department is looking at this crime from all angles, including as a hate crime and as an act of domestic terrorism." Witnesses say Roof talked about black people "raping our women" and left one woman alive so she could tell the world what he did. Federal investigations and potential charges would be on top of state charges against Roof for nine counts of murder and one regarding his weapon.
