The extra-judicial nature of Gitmo pisses all over the sense of justice of which the West should be rightfully proud
Mere specualtion on your part.

How can we know that they are terrorists if there has not been due process?
There was under the articles of the Geneva convention. Would you give them access to US courts?

The term unlawful combatants is also one with which I am uncomfortable.
Again thats how the Geneva Convention classifies them. Once more these rules are made to discourage people from fighting in such a manner. If we all listen to people like Tribesman they would be treated the same as US soldiers. This is ludicrous and makes the conventions worthless. If your not going to be punished for not following the rules why follow them at all?
