Four Hired Guns in an Armored Truck, Bullets Flying, and a Pickup and a Taxi Brought to a Halt. Who Did the Shooting and Why? - washingtonpost.com
"On the afternoon of July 8, 2006, four private security guards rolled out of Baghdad's Green Zone in an armored SUV. The team leader, Jacob C. Washbourne, rode in the front passenger seat. He seemed in a good mood. His vacation started the next day.
'I want to kill somebody today,' Washbourne said, according to the three other men in the vehicle, who later recalled it as an offhand remark. Before the day was over, however, the guards had been involved in three shooting incidents. In one, Washbourne allegedly fired into the windshield of a taxi for amusement, according to interviews and statements from the three other guards."
