At least eight students at The Citadel military college in Charleston, South Carolina have been suspended after photos of them dressed in white hoods surfaced on Facebook Wednesday night. Though Citadel president Lt. Gen. John W. Rosa was quick to explain the incident as a group of students “singing Christmas carols as part of a ‘Ghosts of Christmas Past’ skit,” that excuse looks even flimsier when considered in the context of the school’s racist past.
