As far as human rights groups were concerned the Obama administration got off to a flying start with the executive orders pledging to close Guantanamo and restricting all US personnel to using interrogation techniques delineated in the 2006 Army Field Manual on Interrogations.
Unfortunately this was high point and it has been downhill all the way ever since. While the Executive Order put an apparent end to waterboarding and CIA black sites the 2006 Interrogations Field Manual is itself far from unproblematic.
There is nothing in the manual to prevent the reintroduction of the so-called "frequent flyer" technique of constantly waking and rewaking an individual after only a few minutes sleep so that no effective rest is gained at all.
In the past eight months credible reports have emerged that such techniques are still being used in US military detainee screening centers in Afghanistan. An earlier US Army field manual explicitly prohibited "abnormal sleep deprivation" as a form of "mental torture."
