A former CIA agent who oversaw the capture of the man thought to be Al-Qaeda's third-in-command, has been sentenced to two and a half years in prison for leaking classified intelligence. John Kiriakou was the first to blow the whistle on Washington's torture programme - later revealing the name of an alleged torturer at Guantanamo Bay. The CIA denied the accusations, referring instead to enhanced interrogation techniques. Kiriakou's supporters praise him for exposing the extent of the CIA's use of torture in prisons. Activist and author, Sibel Edmonds, says the U.S. classifies too much data - sometimes to cover-up wrongdoing, and that means insiders making a stand will keep going to jail.
