The Ferguson police officer whom a grand jury has chosen not to indict in the August shooting death of an unarmed teenager said in an interview Tuesday he would not have done anything differently because he was trying to save his own life. In an interview that aired Tuesday evening with George Stephanopoulos of ABC News, Darren Wilson recalled the incident and said “the reason I have a clean conscience is because I know I did my job right.” The sit-down marked his first since Monday evening’s announcement that a grand jury had declined to charge him for the killing of Michael Brown, which ignited bouts of looting and arson in Ferguson despite state efforts to prepare for the possibility of violence.
