[JURIST] Stephen Cambone [official biography], undersecretary of defense for intelligence, on Thursday told the Senate Armed Services Committee [official website] that the CIA will no longer be allowed to hold unregistered "ghost" detainees at US military installations such as Iraq's Abu Ghraib prison [Wikipedia profile; JURIST news archive]. Cambone said the newly issued interim interrogation rules [JURIST report] which require a single standard to be used at all military prisons should eliminate the CIA's practice at Abu Ghraib of hiding detainees and subjecting them to separate interrogation methods. Critics have indicated the CIA tactics are much harsher than those employed by the military. Army investigations into Abu Ghraib blamed the CIA's practices for a loss of accountability, abuse and a poisoned atmosphere at the prison. The CIA [official website], which has come under attack over the pace of its internal investigation into interrogation tactics, declined to comment on the committee's proceedings.
