Nellie and John may have thought the two Johns were hit by different bullets, but they were equally convinced that the three shots came from over their right shoulder, and no where else. And that's very important, because some have claimed that John and Nellie were bought off, and are unreliable. If so, they'd agree that there was only one bullet.
About a third of witnesses said they heard shots from the knoll. Not two thirds, nowhere near it. Many conspiracy buffs have repeated false numbers based on extrapolative conclusions. Witnesses for instance who said they heard shots from the SBD but saw or smelled smoke on the Knoll were classified as saying shots came from the knoll, even when some of them claimed the smoke smelled like exhaust or steam. Over half said they came from the SBD. A few said they came from other places, ranging from the overpass to inside the car itself. Five out of about a hundred thought they came from more than one direction.
Some interesting points: some of those who said the shots came from the Knoll or somewhere else were on the other side of both places (the overpass, for instance) where the sound for either location would have come from the same direction. Zapruder said he didn't know where the shots came from, that the just reverbrated everywhere. That's very important, because we know from his filming that he was on the Grassy Knoll less than ten feet from where a shooter would have had to stand. At one point, he has testified, he heard someone drop a bottle and turned to see a couple on the street, at a point just below the famous picket fence. So he had a clear view of that area, had just looked in that area, and could tell when a sound came from that area. There were no shooters.
Here's a chart:

The wound in the back of Kennedy's shoulder is clearly higher than the exit wound in the bottom of Kennedy's throat, and if you add the fact that Kennedy was leaning slightly forward, it's even more pronounced. Look at the autopsy of Kennedy's front wound--it is clearly below the line of his shoulders.
The emergency room doctors at Parkland had mixed opinions of the wound on his neck. Some said it was an entry wound, some speculated an exit wound, and some thought it was an exit wound from a fragment of bullet from his brain. That's why you don't trust first comments made by people in an emergency--they are guessing. Later examination showed it to be an exit wound.
There were not more bullet fragments in Connally than was missing from the bullet found on Connally. The fragments from a bullet don't come from the tip, they come from the amount of metal squeezed out of the back of a bullet as it is fired (it's called toothpasting). There was more than enough metal missing. Here's one study on it:

http://mcadams.posc.mu.edu/wound5.txtOn the package, Oswald told police he carried his lunch that day, and nothing else. The co-worker who rode with Oswald that day said he did not carry his lunch, but carried a long package, which he said contained curtain rods. When asked the length, he guessed 27 inches, but said he wasn't sure. He repeated that he wasn't sure, several times, and that he had just glanced quickly at it in the back seat. He also saw Oswald carry the package into the SBD, but from about twelve feet away. The rifle, disassembled, would have been 35 inches--not a great difference. A long bag was found next to the rifle near the window. It was long enough to carry the rifle, it had fibers inside it consistent with the fibers of a blanket the rifle had been wrapped in while in Oswald's garage, and the paper was wrinkled in the correct places to mark a rifle. The bag had Oswalds fingerprints and palm prints on it. Six cops witnessed the bag's discovery, and there is a photograph of the bag being carried out of the SBD an hour after the shooting. It is clearly long enough. No curtain rods were found in the SBD, despite an extensive search for them. A rifle was. And Oswald's rifle from his landlady's garage was missing, and to this date, has never been found, if one assumes that this was not the same rifle that killed JFK. So, to sum, the witness who saw Oswald carry the rifle swore emphatically that he didn't know how long the bag was, though he guessed 27 inches, he claimed that the bag the FBI had looked like the same bag, Oswald's prints were on the bag, and the bag carried a rifle like the one missing from Oswald's garage.
So, Oswald lied to his friend about the bag, lied to the police about whether he carried a bag, and had a rifle like the one found at the scene vanish from his garage. As I said somewhere else, the evidence is much stronger that Oswald shot Kennedy than that OJ killed anyone.
Sorry if I missed some points. I saw nothing I haven't seen debunked before, but I am at work and typing this when my boss isn't looking, so it's not thorough.
