It looked like an accident to me. (Can’t pause the tape.)
Is there any reason to believe that this video was not doctored like all the rest?
It is a very badly spliced-together job. Notice how it cuts just after the soldier fires (aiming way to high to hit someone's foot at that angle) and then you see the Pali lying on the ground, and there is no blood on his feet.
It's the usual pile of lies.
