Pittenger explained to BBC News that Wednesday’s violent riots in the North Carolina city following the shooting of Keith Lamont Scott were caused by black residents who were jealous of the success of white people. “The grievance in the [protesters’] mind – the animus, the anger – they hate white people because white people are successful and they’re not,” Pittenger said Thursday.
