LNers Can't Explain the Two Back-of-Head Bullet Fragments

[Tom Graves]

Oswald's first shot at pseudo Z105-110 ricocheted off the overhead signal arm & the jacket split off into two pieces and were found in the limo.

LOL!

[Mitch Todd]

Sorry, but this is total fiction. Again, no FMJ bullet in the known history of forensic science has deposited a fragment, much less multiple fragments, at/near the entry point when striking a skull.

And you get this bit of wisdom from where, exactly?

[Tim Nickerson]

Where does this come from? Can you point to any experiments that support this?

Why is this scenario not possible?:  The FMJ bullet deforms upon striking the skull.  As the bullet penetrates the skull, the part of the bullet behind the nose compresses into the nose.  The back of the WC 6.5 mm bullet is not enclosed so the compression on the nose can cause bits of lead to spill out of the butt-end as the front part of the bullet passes through the skull. (When the bullet is compressed the temperature of the bullet increases so this lead could be in a softened or possibly a liquid state). These bits of lead don't make it through the hole in the skull created by the bullet nose impact so they end up on the outside surface.

Andrew, there were not two fragments imbedded in the back of the skull. Those who examined the X-rays and said that there was even one fragment there were wrong. The "6.5mm" radio-opaque object seen in the anterior X-Ray view was the 7mm x 2mm lead fragment removed by Humes.
