Detainees Shown CIA Officers’ Photos
Justice Dept. Looking Into Whether Attorneys Broke Law at Guantanamo
The Justice Department recently questioned military defense attorneys at Guantanamo Bay about whether photographs of CIA personnel, including covert officers, were unlawfully provided to detainees charged with organizing the Sept. 11, 2001, attacks, according to sources familiar with the investigation.
Investigators are looking into allegations that laws protecting classified information were breached when three lawyers showed their clients the photographs, the sources said. The lawyers were apparently attempting to identify CIA officers and contractors involved in the agency’s interrogation of al-Qaeda suspects in facilities outside the United States, where the agency employed harsh techniques.
