CNN now has a State Department source contradicting other government sources who yesterday said immunity had been given to Blackwater guards by State Department investigators.

Late Update: CNN has walked back its story that immunity wasn't offered and is now reporting that limited immunity was in fact offered by State:

No blanket immunity deal was offered to Blackwater guards for their statements regarding a shootout in Iraq last month that left 17 Iraqi civilians dead, two senior State Department officials told CNN Tuesday.

However, some kind of limited immunity was apparently offered by State Department investigators when they questioned the Blackwater personnel apparently involved in the shootings, the officials said.
