Anatomy wise its pretty inconceivable that he could shoot out his vocal cords and miss the cervical spine which lies immediately posterior with a straight shot. If the gun is angled chances are the vertebral, jugular and/or carotid arteries or veins get clipped or the subclavian blood vessels. That would incur major blood loss being so close to the heart pump. Highly doubtful thats what he did.
Eggs ackley ... but we the people are not supposed to question the official lines now, hadn’t you heard?
