There whole incident has been subject to distortion and propaganda. The truth is no longer relevant.
From my reading and TV reports. Lloyd and the other three blundered into the front line and were arrested by the Iraqis. Two were put in an armed Iraqi pick up which was destroyed by American fire killing them. Lloyd and the Belgian cameraman in the TV truck were fired on by the Iraqis, wounding Lloyd. The cameraman took cover but was fired on by Americans, no doubt under the impression he was Iraqi. Lloyd was picked up by an Iraqi civilian in his minivan. Crucially he also picked wounded Iraqi soldiers.
This van was then fired on by American troops killing Lloyd and an Iraqi soldier. This is the so called 'war crime' the coroner and family is referring to. Firing on the civilian minibus. In fact the driver believes he was attacked by a helicopter. If that was true then he and the van would not have survived.
The coroner and the family obviously believe that in the fog of war you can identify everyone involved differentiate between civilians and combatants and journalists and identify which unmarked vehicles are involved and which are not.
There will be no trials or arrests. It was war. Terry Lloyd knew that. After all it wasn't his first war.
