Open Image ModalIn this photo made from a Sept. 16, 2016 police video, Terence Crutcher, left, lowers his right arm as he is pursued by police officers moments before he was shot and killed by one of the officers in Tulsa, Okla. When it comes to charging an officer, legal experts say, the most important determination isn\'t whether the officer was actually in danger in hindsight. It\'s whether the officer reasonably believed in his or her own mind that they or fellow officers were in danger at the split second they choose to shoot. There\'s no clear, standard formula investigators can rely on to answer the question of whether an officer\'s belief that he or she\'s in peril is reasonable, a former federal prosecutor in Chicago said.
