I don't get it.
WHY would they do this,when they have Afghan counterparts that are accustomed to doing that sort of thing,and who without a doubt understand the nuances of the language MUCH better than the Americans,and are more likely to pick up hints of deceit or even confessions?
Unless maybe the guy they had was a "special case" they wanted to interrogate in secret so they could plan "surprise parties" for his accomplices? IF that was the case,how did anyone else find out about it? SF teams ain't exactly known for blabbing their business to the world.
Or at least they didn't do this back in the 60's. What happens in the team house,STAYS in the team house was the general rule,and should still be the case.
SF teams live and operate way the hell out there,away from other Americans and are outnumbered sometimes by more than 10 to 1 by the locals that live in their camps with them and who are supposed to be their allies. If they want to keep living,they need to keep the faith with each other and not run their mouths. Team unity is EVERYTHING.
