O'Connor's much earlier recollection and signed diagram takes precedence over statements made to Law. That O'Connor would think that the bullet entering above C7 would have come out through JFK's heart and through his sternum suggests that he was definitely on the downslope as far as his mental faculties were concerned.
So NOW you want to Rely on O'Connor's "EARLIER Recollection", when Previously you attempted to perpetrate a FRAUD by misrepresenting what was Depicted on The Autopsy Face Sheet. Pen to paper Medical Evidence with respect to the location of the BACK Wound does Not get any "Earlier" than the Autopsy Face Sheet. Dance Clown, Dance.
