On Capitol Hill, the House has overwhelmingly approved a measure that would subject private military contractors in Iraq to prosecution in U.S. courts. The move comes on the heels of last month’s killing of up to 28 Iraqi civilians by guards working for the private military firm Blackwater USA. The bill would not be retroactive, meaning Blackwater guards would still likely avoid prosecution. The final vote was 389 to 30. If the measure attracts the same support in the Senate, Congress would have enough votes to override a presidential veto.
