When I was young a read a book called "The White Rabbit" which told about how a British airman was tortured by the Nazis by being humiliated and half-drowned. The book frightened me at the time. Then today I read the following:
"FBI officials are so concerned at interrogation techniques being used by the CIA on al-Qaeda detainees that they have advised their agents not to take part in many of the interviews, it was reported today.
The methods, which were authorised by the US Justice Department after the 9/11 attacks, include a technique known as "water boarding", in which a prisoner is strapped down, forcibly pushed under water and made to believe he might drown, The New York Times reported today."
So not only are the CIA borrowing methods from the South African Bureau of State Security; they are borrowing methods from the Nazis.
Not exactly a "rogue element" then.
