Yeah, and I'm really don't like the special treatment for "enemy combatants" as well. Does the right to life, liberty and happiness apply to all mankind or just to people the US government is not currently scared of?
Scared people are scary. Really scary, when backed far enough into a corner.
Enemy combatants belong to non-state actors, and so no treaties or guidelines apply to them. Last I checked Al doesn't Al Qaeda and the rest of the cavers don't get representatives in the UN.
http://www.un.org/en/documents/udhr/index.shtml Article 29(3)
These rights and freedoms may in no case be exercised contrary to the purposes and principles of the United Nations.
See perhaps most recently _Boumediene v. Bush_ http://en.wikipedia.org/wiki/Boumediene_v._Bush
Namely that these enemy combatants do have rights under the Constitution in this case the right to a habeas petition.
The other relevant historic case-law here is _Yick Wo v. Hopkins (1886)_ http://en.wikipedia.org/wiki/Yick_Wo_v._Hopkins "these provisions [the Constitution] are universal in their application, to all persons within the territorial jurisdiction."
