i can't see how you could think of it as a necessary tool, we now its not working as a deterent, and we also know that information obtained under torture has a much greater chance of being false.
However compare to the torture tactics of Savak or Iraqs previous regime it dopesn't seem to be that bad at all....well..they haven't dissolved peoples feet in acids as a method of getting them to talk...yet...
even so, just because it is a slightly lesser evil, doesn't make it right.
Guantanamo bay Is a spit in the face to what humanitarians have been fighting for since the first world war. It totally undermines the International Law built up since the second world war and has totally failed to achieve whatever goals it was trying to achieve. We should all be ashamed that we allow our governments to support the continued exsistence of the guantanamo bay facility
