As I'm reading this... I would just like to simply point out what they thought that day...
For your consideration (From Tom Wicker):
Mr. Kennedy apparently was hit by the first of what witnesses believed were three shots. He was driven at high speed to Dallas's Parkland Hospital. There, in an emergency operating room, with only physicians and nurses in attendance, he died without regaining consciousness.
Later in the afternoon, Dr. Malcolm Perry, an attending surgeon, and Dr. Kemp Clark, chief of neurosurgery at Parkland Hospital, gave more details. Mr. Kennedy was hit by a bullet in the throat, just below the Adam's apple, they said. This wound had the appearance of a bullet's entry. Mr. Kennedy also had a massive, gaping wound in the back and one on the right side of the head. However, the doctors said it was impossible to determine immediately whether the wounds had been caused by one bullet or two.
Dr. Clark was summoned and arrived in a minute or two. By then, Dr. Perry said, Mr. Kennedy was "critically ill and moribund," or near death. Dr. Clark said that on his first sight of the President, he had concluded immediately that Mr. Kennedy could not live. "It was apparent that the President had sustained a lethal wound," he said. "A missile had gone in and out of the back of his head causing external lacerations and loss of brain tissue."
