CIA 'knows more than it can say about bin Laden'

CIA Director Porter Goss, saying his agency struggles to penetrate terrorist sanctuaries overseas, insists that "we know more than we're able to say publicly" about Osama bin Laden and Abu Musab al-Zarqawi.

In a rare television interview, Goss defended the CIA's track record, which has been tarnished by allegations ranging from erroneous or hyped intelligence leading to the war in Iraq to reports the agency runs secret prisons abroad for terrorism suspects and uses harsh interrogation techniques amounting to torture.
