no coverup. The ground patrol was taking fire. Instead of unassing the area the reporters and unnamed others were moving towards the ground patrol. (reporters do that) what looked like a weapon was spotted.
Again this is not your local sherrif stopping a dodgy looking car. Their job was to remove ANY threats to the patrol. War is not policing. If you are uncomfortable about what happened do your best to have the troops removed from the warzone. Dont ask them to be killed on your behalf because it is fugly.
What coverup? I read the after action reports and they were a clear writeup of what you saw on the tape. Under the rules of engagement the actions were reasonable
