Judge dismisses all charges in Blackwater shooting

WASHINGTON U.S. District Judge Ricardo Urbina said Thursday the Justice Department overstepped its bounds and wrongly used evidence it was not allowed to see. He said the government's explanations have been contradictory, unbelievable and not credible.

Blackwater contractors were hired to guard State Department diplomats in Iraq. Prosecutors say the guards fired on unarmed civilians in a busy intersection in 2007, killing innocent people.

After the shooting, the guards gave statements to State Department investigators. Prosecutors were not allowed to use those statements in the case.
