Khalid Sheikh Mohammed, the mastermind of the 9/11 terrorist attacks gave up the name of Osama bin Laden’s personal courier to the CIA after being “water boarded” at Guantanamo Bay, resulting in a raid on a compound in Pakistan where bin Laden was being hidden by the Pakistani government that ended with Osama bin Laden being killed in a firefight.
Abu Faraj al-Libi also an al-Qaeda “leader” held at Guantanamo Bay helped bin Laden find places to hide in various places in Pakistan according to top secret government documents.
Interrogation and torture of Abu Faraj al-Libi led him to give up the name of a courier that led the CIA to the compound where bin Laden was hiding.
So, enhanced interrogation techniques work, I don't care what Amnesty International says.
And thank you, Mr. Obama, for breaking your campaign word to your liberal lovers and keeping the BUSH policies of enhanced interrogations, rendition, keeping GITMO open, and following the surge methods you said you hated.
