If these putzes are there without the sanction of our gov/military, then let the Afghans have their way with them.
What right do they have do detain, let alone interogate people?
You play international bounty hunter, ya takes yer chances.
OTOH, if someone did sanction them, and are now denying it, let them name the people who approved this get dragged down with them.
With the politically correct mess that we euphemistically refer to as the war against terrorism, I don't care about niceties. These people are Americans and if they screwed up let Americans deal with them. When you mention "rights"...maybe they have the right of doing for themselves what their government seems incapable of doing.
