releasing captured combatants seems premature
But that's the point. There's no reason for us to believe that these people are combatants at all other than by taking the word of our administration, who have demonstrated themselves to be untrustworthy.
Regardless, I'm not suggesting that they all be released. All I'm suggesting is that we truly determine whether they're supposed to be there and then treat the ones that really are in accordance with the Geneva Convention, regardless of whether they were illegal combatants or not. The letter of the law should be a baseline for how well to treat people, not the ceiling.
