June 7, 2012 Supreme Court Rejects Challenge by Blackwater Operatives Charged in Nisour Square Killing ------------------------------------------------------------------------------------------ The Supreme Court has refused to hear a challenge to a case accusing four operatives with the private military firm Blackwater of killing civilians in the 2007 massacre at Baghdad's Nisour Square. An appeals court reinstated the case last year after a lower court dismissed it in 2009. The Blackwater operatives are charged for the deaths of 14 of the 17 Iraqi civilians who died when the operatives indiscriminately opened fire. .
