That's exactly why they were at secret locations OUTside of US legal jurisdiction.
Unless you have a very weird legal code, I think that you will find that the perpetrators of any "torture" that happened in these "secret locations" are indeed in a "criminal prosecution scenario." Whether they be Service personnel, Civilian contractors, or local enthusiastic participants of such past times, they are all subject to law, be it Military or Civilian. Whether such law is ever enforced is of course another matter, hence the hypocrisy upon which BB and I concur.
