No suprise that it was an eddited version
There is an unedited version of the video which is 39 minutes long and unsurprisingly has a bit more to it.
The troops you see arrive on the ground were taking fire while they were down the street and the group of individuals did have weapons and an RPG not just cameras. It looks very much like they were are were going to start firing at the troops down the street.
The van has no "ambulance" marking of any sort and looks very much like they were trying to remove wounded and weapons from the area before ground troops could get on scene. Having kids in a vehicle driven into an active engagement is just stupid of the parents.
In the unedited video ground troops do report an unexpended RPG round partially under a body. A RPG round can not be mistaken for a camera or lens up close.
What were these reporters doing in this group with an RPG and AK-47s? Were they trying to capture "An insurgents view"?
People express concern and outrage about the callous manner in which the American forces killed their targets. They took out several people who were trying to fire on their fellow soldiers why shouldn't they be happy with their efficiency. I never hear anybody complain when an insurgent explodes an IED or snipes an American or Allied troop on film and practically dance and sing about it.
