Category talk:Guantanamo captives
It was the official US position that none of the Guantanamo captives were ever entitled to the classification, as per international law. And the USA never treated them as POWs. They did not have article 5 Tribunals. They were not protected from extreme interrogation techniques, knowledge of their capture was withheld from their families.
Should they have been treated as POW? Many legal critics and human rights critics assert that they should have, that international law as well as the USA' domestic law, required this. But the SCOTUS never ruled on this. Neither has any international body. So, personally, I think including them in Category:Prisoners of war is a stretch.
