I do not believe that exhibit that they came up with was the actual bullet. It was too consistent with a round shot into gel or other soft targets. This bullet being the lynchpin of the whole scenario, it makes me again wonder about the credibility of the final results of the official investigation, if not the hypothetical validity of the magic bullet theory itself.
Yeah... it's possible ... It could of happened that way, just... not very likely with that bullet, ( in my opinion of course ).
Many others have argued this same point - which opens the whole can of worms. Obviously this particular bullet was the one found at Parkland Hospital. It is the one that the Warren Commission foccused on in coming up with their theory. If it had been another bullet that made the wounds -where did it go?
Any bullet or bullets fired into Kennedy or Connally would have either remained in their bodies, or would have exited inside the limousine, possibly causing damage to the vehicle interior and/or remaining inside the vehicle for recovery.
The Commission Exhibit bullet was reportedly found on Connally's gurney and cleaned of all blood by someone at the hospital before being handed over to a Secret Service agent at the Hospital. In all the confusion, that person's name was never taken. So, from the start, there is a problem with the chain of custody.
But think of all the many unforseeable factors that would have had to go into such a conspiracy to be able to remove the real bullet and plant a fake. Not that some conspiracy buffs haven't tried to explain it in this manner. (Some claim that Jack Ruby was at Parkland and planted it.) How could anyone know in advance to have a bullet waiting at the hospital? And wouldn't planting one there potentially add an additional piece of unaccountable evidence? After all, a person standing by with the fake would have no idea how many shots were fired, nature of wounds, etc.
Ballistic tests into geletin are designed to try to simulate various things, but just look at any collection of bullets fired into geletin (or any kind of material). No two are exactly the same.
You are correct to state that the single bullet theory is an extremely important part of the Warren Commission's final report. If one bullet did NOT wound both men, then there would have had to have been more than one rifleman, - not a conclusion they wanted to make. They, however, had the evidence to deal with, and came up with their theory.
Their biggest problem was that they stated that it was the FIRST shot which struck the men, and that the SECOND shot missed. In fact, the most likely scenario was that the first shot was deflected and riccocheted, while the second shot was the one which hit both men. Trying to make the first shot the one that hit, compresses the amount of time that the shooter would have had, and it gives you the unlikely "gap" of time between Kennedy's first reaction to that of Connally.
