Afghanistan should be looking at their own men here rather than NATO's. True there was poor communication between NATO and Afghanistan in the implementation of challenging unidentified parties. But seriously, it isn't like the Afghan troops didn't know there were forces in the area other than them and the Taliban.
Seriously, how did you just assume it was the Taliban and not challenge the patrol?
