"U.S. special forces accused of abusing prisoners in Iraq threatened Defense Intelligence Agency personnel who saw the mistreatment, according to U.S. government memos released Tuesday by the American Civil Liberties Union. The special forces also monitored e-mails sent by defense personnel and ordered them "not to talk to anyone" in the United States about what they saw, said one memo written by the Defense Intelligence Agency chief, who complained to his Pentagon bosses about the harassment. In addition, the special forces confiscated photos of a prisoner who had been punched in the face. Prisoners arriving at a detention center in Baghdad had "burn marks on their backs" as well as bruises and some complained of kidney pain, according to the June 25, 2004 memo.
