A black jail, a U.S. military detention camp to interrogate high-value detainees, was established at Balad in summer 2004, named the Temporary Screening Facility (TSF). A British Secret Intelligence Service (MI6) lawyer who visited a black jail, believed to be at Balad, described it as holding prisoners in wooden crates, too small to stand in or lie down, who were subject to white noise. General Stanley McChrystal, commander of Joint Special Operations Command, regularly visited the site, reporting that the staff of interrogators and analysts was six times the number of detainees, enabling important detainees to be questioned through each shift.
