It is just a little ridiculous. Amend that, a LOT ridiculous. You know, there is a lot of partisanship involved in this. Democrats are trying to make Republicans look bad, and it doesn't matter that the security of the US citizen and the health of the United States is damaged thereby, so long as the political prospects of the Democrats are enhanced. It may be that the Republicans seek their political self-interest with such disregard of national interests, but I don't think so. I guess part of the issue is that silly Democrats actually buy this stuff. More important to guarantee the rights of some dastardly monstrosities than to attend to the safety and security of the nation. Not in my book.
The whole context of the Geneva Convention accords is "orderly war," war where combatants wear uniforms, where leaders wear insignia, where the enemy is also signed on to the Geneva Convention. I fail to see how this applies in this case. What army does Sheik Mohammad whatzisname a soldier in? What nation-state claims him as a member of its military? What consideration does Al Quida provide to the enemy combatants it captures? Does it guarantee that it will behead its prisoners with a well sharpened sword to diminish pain?
And let's be serious, suppose it is "bad" and "naughty" to "mistreat" these prisoners. Remember, we aren't attaching arc welding electrodes to their twig and berries. On the continuum from good (Jesus Christ and/or Mother Teresa and/or Mahatma Ghandi) to evil (Adolf Hitler), where does this action sit? I would guess a lot closer to the good than the evil of, for example, the holocaust and killing 3 million jews in concentration camps or waging aggressive war of conquest destroying vast personal property and leading to the death of 20 million Russians. Come on!!! It ain't a big deal!
