No, believe me, there is a difference, in one you know they were innocent, in the other one, nobody's got a clue. As far as I recall, in liberal democracies like the US, you are innocent until proven guilty. Since nobody's got a clue, I don't see any reason to believe they were guilty of anything. Had they been tried in a court of law, at least you could remove some of the doubt, but since they never were, then there's no difference, between one innocent man being killing himself in captivity and another innocent man killing himself in captivity.
The big difference is that when the American army is the captor, it's ok. If it's not, it's not ok. Both are bad, in my opinion.
