During WW2, when the Japanese captured some of the Dewey Raiders, they gave them a trial, provided them with defense lawyers, and found the flyers guilty of war crimes. They were tortured and shot.
In Iraq, Saddam Hussein was given a trial, defense attorney, allowed to confront his accusers and speak at his own trial in his own defense.

I agree that the decision makes it problematic for the gov't to simply arrest someone, put them away "in cognito" for as long as the "War" is going on. (Think about that, though.) Then, if they die in custody or are injured, the gov't has created a law that says they can't be held responsible.
