2 Americans CAN sue Donald Rumsfeld after 'being tortured by US army in Iraq'

Vance and Ertel had been hired by Shield Group Security, an Iraqi firm who the duo believed were involved in some questionable dealings, including illegal bribery and other corruption activities.

They flagged up their concerns to the U.S. authorities and began co-operating with the Federal Bureau of Investigation - and in early 2006 they were taken into custody and slung into Camp Cropper, the notorious holding facility for security detainees near Baghdad International Airport.
