US Attorney General Eric Holder has
ordered a "preliminary review" into the secret detention programme operated by the CIA after
the attacks of 11 September 2001. It's a welcome first step but it's not enough, says Amnesty International.
Santiago Omar Riveros, who ran a detention centre, was found guilty of torturing and beating to
death a 15 year old boy. He is also accused of over 40 crimes against humanity involving victims of the era's so-called "disappeared".
