I have no problem holding actual POWs or enemy combatants until the end of a conflict or until they are in Depends, whichever comes first.
However, these guys were captured by bounty hunters in Afghanistan. They are from a group fighting the Chicoms, not the US. Multiple courts have ruled they are not a threat to the United States, including panels with a majority of conservative jurists.
You cannot just knee-jerk reactions here. Just because liberal pinheads attack Gitmo, it does not mean that all persons held in Gitmo SHOULD be held there as enemy combatants. And it isn't that long a trip from being set up as a foreigner for indefinite detention to being an American citizen being set up for indefinite detention. Do you REALLY want this kind of power in the hands of a President Obama, if there is another OKC-type bombing? He'd just declare conservative activists to be domestic enemy combatants and it's down the memory hole for us.
Members of this group were at a camp in Tora Bora set up by AQ and the Taliban. Some fought the US. Some took part in the Mazari Sharif uprising that led to the death of a CIA officer. They have since attacked guards at Gitmo.
Let them rot.
