Schmitt, Eric. “Pentagon study describes abuse by units in Iraq.” The New York Times, June 17, 2006.

Summary: American military investigators from Special Operations groups tortured Iraqi detainees in early 2004. A inquiry by Brigadier General Richard P. Formica, completed in November 2004 but suppressed by the Pentagon until the ACLU used the Freedom of Information Act to extract it, determined some of the facts: We fed prisoners nothing but bread and water for as long as seventeen days. We stripped them naked, poured water over them, and interrogated them in cold rooms. We enclosed them in cells four feet high, four feet long, and twenty inches wide for days -- as long as a week, in two cases.

General Formica recommended that none of the individual soldiers who performed these acts be disciplined in any way, since, in his judgement, they believed that they were following standard American military policy, acted without cruelty or malice, and were working in a dangerous environment.
