We will never know the whole story. But, the photos are curious.
I have a hard time believing those guys where shot and searched there. I see no boot imprints from blood on the ground.
Any person walking around that area would have picked up blood from the bodies and from searching the compound.
Curious.
I am with you, Pat Tillman was shot three times in the face by plainclothes soldiers on our side(aka Delta or other SpecOps). So "Friendly fire" is technically correct but it was no accident. It's no secret he was due to come back home and he was not happy, much like the cluster f*ck that was Vietnam 1968, Afghanistan was\is a confusing morass of non specific goals and sometimes conflicting orders and Pat Tillman was very disillusioned.
