Not every bullet has to have an exit wound. When you look at the evidence, the bullet in the back didn't exit, the "bullet" in the throat didn't exit. The only bullet that went through was the bullet to the temple and the bullet that hit Connally.
Fascinating. Then why didn't they show up on the neck X-rays?
Oh, right, they must have been those "invisible-to-X-rays" bullets that were so common in 1963. And the shooters (plural) who made those shots chose to use these magic bullets (!) while the other shooter(s) (that's 3+ so far) used ordinary metallic bullets because... um... they liked variety?
Oh, wait, I know -- because despite the fact that the conspiracy theorists all claim that even hitting a "moving target" at all was somehow an "impossible" shot, you'll have us believe that the "additional" gunmen were such perfect shots that they *knew for certain* that they could make shots on a moving target so precisely that they could put them into JFK's neck from two different angles so perfectly that they could create the illusion of a single in-and-out pass-through shot, thus "hiding" their handiwork, because they knew for certain that the doctors weren't going to probe the neck wound too thoroughly *and* that the magic un-X-rayable bullets would have no chance of passing through the neck and spoiling the illusion. What a perfect plan!
Do you guys even *listen* to yourselves?
Oops, wait, they found metallic bullet fragments in the neck wound after all:
EXAMINATION OF X-RAY FILMS[...]
Films #8, 9 and 10 allowed visualization of the lower neck. Subcutaneous emphysema is present just to the right of the cervical spine immediately above the apex of the right lung. Also, several, small metallic fragments are present in this region. There is no evidence of fracture of either scapula or of the clavicles, or of the ribs or of any of the cervical and thoracic vertebrae.
The foregoing observations indicate that the pathway of the projectile involving the neck was confined to a region to the right of the spine and superior to a plane passing through the upper margin of the right scapula, the apex of the right lung and the right clavicle.
