Yep - during a time of war people are torturing prisoners, sometimes to death. We executed people for that. People who said they thought what they were doing was justified and / or legal.
I'm sorry but the CIA torturers are war criminals, it doesn't matter about the relative aspect of it - there absolutes.
For the sake of a few thousand people, a fraction of those killed in gun violence for instance, the USA sacrificed any claim to moral superiority and probably created many more terrorists than were ever stopped. Home of the brave indeed.
I'm British, in the military and a massive ally of the USA, but on this issue the lack of contrition exhibited is shameful.
