This political correctness at its most pathetic level. Letting Americans be tried in an Afghan court is masochistic. It's like the perpetual guilt of the "wine & cheese" set. Oh yeah, I'm sure the Afghans see this as a sign of strength!
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.
