The two doctors at Parkland hospital trying to save JFK’s life were young on-duty emergency room surgeons and not forensic gunshot wound analysts and they testified to that fact to the Warren Commission.
Their duty was to simply save Kennedy’s life and not make detailed observation or notation of trauma in post-surgery documentation after Kennedy was pronounced dead. That’s the job of a coroner’s inquest performed at great length in Bethesda Naval Hospital by the assembled members and their staff:
Commander J. Thornton Boswell, MC, USN: chief of pathology at Naval Medical Center, Bethesda.
Commander James J. Humes, MC, USN: director of laboratories of the National Medical School, Naval Medical Center, Bethesda. Chief autopsy pathologist for the JFK autopsy. Officially conducted autopsy.
Lieutenant Colonel Pierre A. Finck, MC, USA: Chief of the military environmental pathology division and chief of the wound ballistics pathology branch at Walter Reed Medical Center.
No autopsy was performed at Parkland Hospital in Dallas by Jackie kennedy’s demand. Jackie Kennedy refused to leave Dallas without her husband’s body and wasn’t outside the view of her husband’s remains until the jet carrying JFK’s corpse returned to Washington DC. Aside from the ten minutes she accompanied Lady Bird Johnson to the swearing-in of LBJ, she wasn’t out of sight of the casket her husband was placed in. This, according to wackjob conspiracy author David Lifton was the critical few minutes that a team of surgeons entered the guarded US Air Force jetliner and performed the creation of a fake head wound to JFK’s corpse to frame Oswald for the murder. Absolute madness, but people like spooky conspiracy theories so much his book became a best-seller anyway.
What does Dr McClelland of Parkland say? He was a senior ER doc and a med faculty member, I believe
Lipton was a confusing mess. But that does not change the fact that we can see the president’s head explode because of a hit from the front. That is why motorcycle police were sprayed with his blood and brains and that Jackie was trying to crawl on the trunk of the car to retrieve part of his head. Had he actually been shot from the back it would have all gone the other way, into the car.
