I have to say that I don’t know. But torture is “institutionally” non-English, and does not originate here. Asia, and other places, are where the Europeans learned it, from having undergone it by defending against invasive incursion in things such as Crusades (I am not allowed to say against what we were defending, for then my son would get suspended from his history course.) And to _not_ torture while investigating, is essentially an English practise. Read your Paul Johnson: “The Offshore islanders” – chapter ref: “this Realm is an Empire”.
This article here is full of implications and non-sequiturs. You lazy indolent buggers out there had better read the entire thing. The (shifty-looking) [allegedly] “up for it” guy ( = dude) walked off the plane, in the UK, to his family and to his “law_yers” (if you wozz a state, wott seriously, regularly, “did” people, in the basement of the “Ministry” for a living, really, like Nazi Gramsco-Marxian scumbags habitually do) then would you let a torturee do that? Walk off the plane in front of camerae? No, I would not either) but the text implies he was tortured at the command of the British “security services”.
There is, as my old co-director used to say about bailiffs, Health-and-Safety-Gestapo, and other fascistically-motivated non-marketeering State-predator-scumbags who used to be paid, out of our taxation, to psychologically-torment us and functionally-impede us in the course of our business, “MORE TO COME ON THIS ONE, SON”. I take great exception to the entire thing, but I will report back tomorrow when it has all got cooked a bit more and I can smell the rats floating in the air.
