Those who refuse to explain where the bullet went after it hit President Kennedy's upper-back and came out his neck beneath the adam's apple are "implying" the missile stayed inside his body.
Certainly the only logical argument put forward by the WC was to have a magic bullet introduced to make
7 wounds in total. This bullet needed to be found and came to be known as CE399 and introduced to support a lone gunman scenario. It appears to be a FMJ (full metal jacket) that tumbled out of the abdomen and lost a few grains in JC's leg! His muscular leg rejected the rest onto the gurney where it was found later, although a few grains did somehow leave the bullet during its tumble and penetrated the leg - narrowly missing the femoral artery!
The car was never examined as a crime scene and a thorough examination top to bottom was never undertaken by photograph. The SS moved it away, just like they did JFK's body very quickly. I believe the neck wound (covered up conveniently by a tracheostomy) was in fact an entrance wound. The bullet exited out the back side and into the car, possibly upholstery behind his back. There were only 3 shots claimed to have occurred and the first one was a wild shot that hit somewhere on the road - no pictures of damage of it had been seen - only reports! No one was sure if he missed the car by 2 inches or by 20 feet!
