There is a law in physics that says that every action has a opposite and equal reaction. This is also true in politics. And, the apparently political Supreme Court's decision about the Guantanamo Bay detainees will have it's equal reaction; mostly negative.
My guess is the the battle field capture of opposing forces by our own military will cease rather than play games with some Federal judge to obtain approval for detainment. The enemy will either be shot dead without any risky attempt to capture them alive or, if they do surrender, they will be immediately handed over to interrogators of some other country. In either case, the comfy quarters and the rules of interrogation by United States forces will be forfeited. There will be no 3-square meals, prayer time, clean cells, exercise periods, and fresh clothing; as was the case in Guantanamo Bay.
This is what those dancing-in-the-streets liberals have doomed all enemy combatants to as a result of this extremely "bad" Supreme Court decision; a decision based more on hating Bush than good law. The consequences of that decision are both far reaching and, as is the case with almost all Supreme Court decision, irreversible. Mark my words!
