WASHINGTON -- Blackwater guards fired dozens of shots into cars and people, an FBI expert testified Thursday, in an example of the brutality of the 2007 killings that left 14 Iraqis dead in Baghdad.
Paul Slough, Evan Liberty, Dustin Heard and Nicholas Slatten appeared dressed in suits and ties before a federal court in Washington as the second trial in the case entered its fifth week.
Slatten, 32, is charged with the first-degree murder of a civilian. He faces life in prison if convicted. Slough, Liberty and Heard are accused of voluntary manslaughter of the 13 other victims.
All four have pleaded not guilty.
The Blackwater employees were guarding a US diplomatic convoy when they opened fire, killing 17 unarmed Iraqi civilians according to an Iraqi investigation, or 14, according to the US count. The hail of gunfire also wounded 18 people.
Six of the guards had started the shootings.
