3. The Surgical Altercation Theory
Perhaps one of the... queasiest conspiracy theories out there is that which purports Kennedy's blood-soaked corpse was surgically altered to make it appear as though he was shot only from the rear. Had evidence survived to the contrary, that the shot was fired from any other direction, the theory of there being more than one shooter would almost certainly have been proven correct. American author David Lifton once presented the scenario that Kennedy's corpse was removed from its original bronze casket at Air Force One and placed in a shipping casket, where it was covertly taken by helicopter to a secret location where the wounds were surgically altered to comply with the lone-shooter assertion. A crazy theory, but a downright compelling one nevertheless.
