One of the biggest and most explosive clashes at Guantánamo Bay has been fought not between guards and prisoners but between US interrogators, the leaked files reveal.
It was a fundamental clash of cultures: between those who stuck rigidly to US law and those who, in the frightening post-9/11 world, adopted techniques from a US manual detailing psychological and physical torture used by China during the Korean war.
In theory there was – and still is – a simple command structure at Guantánamo, run by the commander of the Joint Task Force Guantánamo (JTF GTMO in military jargon). But in reality there were lots of agencies at the naval base in Cuba, sometimes working together but more often at odds and at times barely speaking.
On the ground alongside the JTF GTMO interrogators were the Criminal Investigative Task Force (CITF), an elite unit, many of whose members had a law enforcement background and opposed the use of harsh methods.
Also in the mix was the CIA, which George Bush made the lead agency in spite of its failure to stop 9/11. Jostling for a piece of the action were the FBI and the Behavioural Science Consultation Team, a group of psychiatrists and psychologists set up by the defence department. The files confirm that interrogators were also present from foreign intelligence services.
