[JURIST] Documents released Tuesday by the ACLU pursuant to a Freedom of Information Act proceeding say that Defense Intelligence Agency personnel in Iraq who witnessed abuses of prisoners by a US Special Forces team were threatened to prevent them reporting those abuses, had their car keys taken and e-mails monitored, and were warned not to leave their base. See a scanned copy of DIA chief Vice Admiral Lowell E. Jacoby's June 25, 2004 memo to the Under-Secretary of Defense for Intelligence here [PDF]. Other documents show what the ACLU claims was a "rift" between the FBI and military authorities about appropriate and effective methods of interrogating prisoners. The ACLU revelations come a day after AP obtained a letter from a senior FBI counterterror expert complaining of "highly aggressive" military interrogations of prisoners at Guantanamo as early as 2002, previously reported in JURIST's Paper Chase. The ACLU press release on the documents released Tuesday is here. The documents themselves, and other torture-related materials obtained through ACLU FOIA reveals, are collected here.
