Hmm. Constitution and the laws based off of the Constitution do not take terrorists as enemy combatants.
This said, by the laws and Constitution of this nation, he is a civilian, not a soldier.
Due to this fact, we must either, 1) Amend the Constitution to enable military prosecutions of civilians, or 2) work with what we have.
I would rather not allow some politician, or members of the government, to declare me, or you, a terrorist, and therefore get the military tribunal, instead of civil courts with their Constitutional Protections...
Yet, you allow this adjustment, that is what you will get. (Example: TSA illegal search and seizures... I am waiting on the cavity searches, as soon as someone tries a butt bomb...)
Besides, did Timothy McVeigh get away with it in Civilian Criminal Court? No.
I would rather say this: The fellow got off of the counts because 1. Lack of Evidence 2. Lack of a good prosecutor. 3. Length of time held and lack of Habeas corpus rights given to the claimed terrorist.(Both the time and the denial of rights Constitutional violations? Yes.)
I bet we will find there are a lot of non-terrorists being held in Gitmo... And we will reap the benefit of that in the eye of the world...
International Court? No, thank you. The moment we rely on them, is the moment our justice system will become secondary to them...
