Only a handful of the 54 investigations of alleged detainee abuse and other illicit activities detailed in the documents led to recommended penalties as severe as a court-martial or discharge from military service. Most led to administrative fines or simply withered because investigators could not find victims or evidence.
Soldiers admitted to beating detainees and threatening to kill them. I assume Smith and White mean additionally that the Soldiers had the detainees under their control. If so, administrative fines don't get it.
Ditto for stealing money from civilians. Not the way to win hearts and minds.
