Either the case can be made for military tribunals or civilian courts, but not both.  Either they are terrorists subject to violating U.S. laws or they are enemy combatants captured by invasion and occupation forces defending their country and face military review.

But I guess the USA prosecutors want show trials featuring the most attention getting viewable detainees.  And they pick the northeast court district to seal the outcome and the payrolled judges who will go along to get along. 

Should be quite a performance.
