You took the words right out of my mouth. Why is the situation "spiraling out of control" when the fanatics we need to exterminate are being executed by the very people THEY were executing last week? The Northern Alliance has very good reasons to hate these people, who have shown no mercy to their foes and only recently assassinated Massoud.
It's never a pretty sight when a lynch mob of former victims turns on their oppressors, but these guys surely asked for it.
