Military Intelligence
[Major General Antonio] Tagubas report listed some of the wrongdoing:
Breaking chemical lights and pouring the phosphoric liquid on detainees; pouring cold water on naked detainees; beating detainees with a broom handle and a chair; threatening male detainees with rape; allowing a military police guard to stitch the wound of a detainee who was injured after being slammed against the wall in his cell; sodomizing a detainee with a chemical light and perhaps a broom stick, and using military working dogs to frighten and intimidate detainees with threats of attack, and in one instance actually biting a detainee …
[Staff Sergeant Ivan] Frederick repeatedly noted that the military-intelligence teams, which included CIA officers and linguists and interrogation specialists from private defense contractors, were the dominant force inside Abu Ghraib. In a letter written in January, he said:
I questioned some of the things that I saw … such things as leaving inmates in their cell with no clothes or in female underpants, handcuffing them to the door of their celland the answer I got was, “This is how military intelligence (MI) wants it done” … MI has also instructed us to place a prisoner in an isolation cell with little or no clothes, no toilet or running water, no ventilation or window, for as much as three days.
The military-intelligence officers have “encouraged and told us, Great job, they were now getting positive results and information,” Frederick wrote. “CID has been present when the military working dogs were used to intimidate prisoners at MIs request.”
…
Sergeant Javal Davis [said] “I witnessed prisoners in the MI hold section … being made to do various things that I would question morally … We were told that they had different rules.” Taguba wrote, “Davis also stated that he had heard MI insinuate to the guards to abuse the inmates. When asked what MI said he stated: Loosen this guy up for us … Make sure he has a bad night … Make sure he gets the treatment.”
