In January 2004, U.S. Army reservist Sergeant Joseph M. Darby gave two CD-ROMs containing photographs of prisoner abuse at Abu Ghraib to Special Agent Tyler Pieron of the Army Criminal Investigation Command. Darby, serving with the 372nd Military Police Company, said the images violated the rules of war and triggered an investigation that implicated multiple soldiers, including Charles Graner and Lynndie England, in conduct contrary to the Geneva Conventions. His disclosure became a central catalyst for public exposure of the abuse scandal.
Darby had been assured anonymity, but his identity was disclosed after The New Yorker published his name and Defense Secretary Donald Rumsfeld identified him during a Senate hearing. Darby and his family subsequently faced harassment, property vandalism, death threats, and protective custody; Rumsfeld later wrote asking him to stop discussing the disclosure of his identity. Darby received the John F. Kennedy Profile in Courage Award on May 16, 2005. The episode demonstrated both the importance of internal evidence reporting and the institutional failure to protect a military whistleblower after allegations of severe detainee abuse became public.
