If anyone wants to spend 50 minutes in shocked horror and ruin their day, this documentary about thousands of Talaban prisoners murdered in Afghanistan under the supervision of U.S. Special Forces and dumped into a mass grave ought to do the trick...
Warning- people being massacred with hands tied behind backs, hundreds of dead bodies, extremely painful and real footage
If anybody would like the other side of the story I'd suggest Marcus Luttrell's best seller, 'Lone Survivor'. It paints an accurate picture of the 'Taliban' that is ignored in US media.
