No. They do not. Note the sub-heading from this online article about military action shifting to Mosul:
Falluja Mosque murder
The US military said it was investigating the fatal shooting of an unarmed, wounded Iraqi by a marine in a Falluja mosque over the weekend.
The inquiry was launched after videotaped pictures taken on Saturday by NBC showed the incident during an operation of the 3rd Battalion, 1st Marine Regiment.
The marine was removed from the battlefield pending the results of the investigation, the military said. aljazeera
Obviously, they have already decided, and are telling their audience, it was murder.
