256 prisoners held at prisons in Iraq, including Abu Ghraib, filed a lawsuit on Monday against the private military contractor, CACI. The suit alleges the prisoners were repeatedly sodomized, threatened with rape, kept naked in their cells, subjected to electric shock, attacked by unmuzzled dogs and subjected to serious pain inflicted on sensitive body parts. The suit alleges that employees of CACI directed soldiers to mistreat the prisoners. [includes rush transcript]
