State Department investigators looking into the killing of 17 Iraqi civilians have offered the Blackwater mercenaries limited immunity deals. Why investigate at all if you're going to do that? If you're one of these murderers why do you need immunity? They're above both U.S. and Iraqi law. Their only legal threat would be war crimes trials.
This, again, illustrates the fantasy that Iraq is sovereign. The crimes happened in Iraq and the victims were Iraqi. Why would the State Department even be involved in prosecution?
The FBI is now prevented from obtaining information from the guards because nothing they said after being given immunity can be used against them. They cannot be tried based on that information. Essentially, the State Department jeopardized any other investigation because they chose to protect their hired mercenaries, likely to save them further public embarrassment. This is one more example of this Administration being more concerned with covering their butts than caring about anything else. The overriding philosophy of this Administration is "don't get caught."
