Iraq Wants Blackwater Security Guards Out

All US diplomats are banned from leaving the Green Zone by land as Iraq's Prime Nouri al-Maliki Minister tells the State Department to fire Blackwater USA security guards. Iraq says ten civilians were killed on Sunday when Blackwater guards fired indiscriminately into a crowd. Blackwater says they shot at "armed enemies." It's the latest in a long series of incidents that have infuriated Iraqis from the streets to the corridors of power. Why is the State Department so dependent on private guards? Has it failed to exercise appropriate oversight?
