WASHINGTON (AP) — Four Blackwater security guards on Monday rested their defense in the shootings that killed or wounded more than 30 Iraqis seven years ago in Baghdad.

Closing arguments will be later this week in the prosecution of the four guards. One, Nicholas Slatten, is charged with first-degree murder. Three others are charged with voluntary manslaughter, attempted manslaughter and gun charges — Paul Slough, Dustin Heard and Evan Liberty.
