No dispute that he was armed. What is in dispute was whether he was reaching in to pull his gun or was he reeling around from being shot? He as shot by two shooters on either side of him.
If he had drawn his gun, then BAM! He’s dead. But if he was killed before any of that happened, then some stupid rookie troopers need a disciplinary hearing.
They can’t prove he drew his gun, so they got themselves a problem. Their best defense will be to pin it on the FBI boys that had an attitude to carry out a hit.
