The US is at war with Islamic terrorists who continue to make war on US interests both domestically and internationally. Nothing is more appropriate to a state of war than POW (prisioner of war) camps, and there is no place so appropriate in this war for a POW camp than Guantanamo. Having actually been there (although not as a prisioner), I can assure you that it is hardly Siberia). Since these are POW's and the war is still on-going (unless you are in contact with Osama Bin Laden and have accepted his surrender), it is rarely appropriate to submit these POWs to crimial trials, unless there were specific crimes in question, and not just the simple fact of making war on the US. Torture is of course, another question entirely, and should never, ever be done as punishment or revenge. On the other hand, what seems like torture to one person could very well be another person's idea of tough, smart, fair, and justified interrogation techniques.
