Did State knowingly grant Blackwater non-grantable immunity?

The State Department’s grant of limited immunity to Blackwater mercenaries may have screwed up an FBI investigation because State didn’t have authority to grant any such immunity.

Wunderbar.

Right now, I’ll give you 50-50 odds that somewhere in the bowels of State, somebody knew about this whole thing in advance. And specifically ordered the immunity grant to screw up the system.
