For four years, 2003-2006, the CIA ran a program to turn Al-Qaeda members trapped in Guantánamo into double agents. The latter were trained in a secret facility located on the military base, known as "Penny Lane".
According to the officials who divulged the information, this program has conditioned enough terrorists to become informants, thereby serving as precious assets during the arrest or execution of Al-Qaeda leaders.
However, this narrative is actually a smokescreen: the majority of the prisoners in Guantánamo never were members of Al-Qaeda. The goal of the Guantánamo torture facility was never to extract confessions, but to contrive them. The few individuals whose formatting was a durable success were used as double agents.
