He shouldn't have reported it... PERIOD!!
Even if I saw what I thought was a war crime perpetrated ON a WAR CRIMINAL, I would have taken it to my bunk and lumped it. I would have lived with it and not teared down the brave marines putting their lives on the line.
Cowboys, maybe, but soldiers or marines do not have the option.
That would have been the proper action. Ignore this bit of drama and drive on. This reporter is a chump fool who has given the enemy material to work with
