Everyone knows the truth: MI6 officers sat around or strolled the corridors while British citizens were being tortured for them. Perhaps curiosity never got the better of these agents and they never peeped in as the finger nails came out; I tend to doubt that.
Miliband lied when he claimed the government never participated in or condoned torture. The truth is that New Labour are as intensely relaxed about electric shocks applied to the genitals as they are about corruption and income inequality.
Next to the crimes which British government ministers, MI6 and its specific agents have committed (all three share culpability) the so-called guidelines under which these people were supposedly operating are almost irrelevant.
