First their countries don't want them back. Second, they have no constitutional rights. Third they are enemy combatants you can hold them as long as the "war" is in progress. Forth, the main reason you can not put them on trial, especially a civilian trial is inadmissibility of evidence or even lack of evidence under the US criminal court laws. You and others seem to be fixated on "trial". When were enemy combatants ever put on trial for just being enemy combatants?
First of all, some of them simply weren't "enemy combatants" unless one wants to extend that definition to anyone that happened to associate with some who might have been. This is what a trial can determine.
Secondly, whether their countries want them back is irrelevant.
Thirdly, I never said they had constitutional rights.
Fourthly, if there's a lack of evidence, then I'd suggest that they should be released.
Fifth, I'm "fixated on trial" because we are "fixated" in this country on making sure we don't incarcerate the wrong people-- that's what trials are for.
And finally, if your son or daughter was being held in a foreign country without trial and who may or may not not have been directly involved in any military action, would you be taking the position you are taking? Hardly, and you
know you wouldn't.
For those who support our retaining them without trial when we are technically not at war, think about this. Think about what if it were your son or daughter. Think about what if it was another American held without trial and being detained for over 10 years. And after thinking about it, and if one still disagrees, then at least don't whine when leaders in another country incarcerate Americans without legal process or with a trumped-up legal process.
