Derek Chauvin’s police supervisor, Sgt David Pleoger, has told his murder trial that there was no justification for the officer to keep his knee on George Floyd’s neck for nine minutes. Ploeger arrived at the scene shortly after Floyd was taken away by ambulance, said that Chauvin and other officers holding down the 46-year-old Black man should have stopped using force once Floyd stopped resisting. “When Mr Floyd was no longer offering up any resistance to the officers they could have ended their restraint,” he said
