Although I suppose the medical team had to try resuscitation, in reality Kennedy was dead the moment the bullet literally blew a portion of his brains out. Some autonomic body functions continued for awhile because the wound did not affect the lower parts of the brain, but even in our time of advanced medicine, no one could survive that damage to the head.
