CE399 was NOT the bullet found by Darrell Tomlinson on a stretcher in Parkland Hospital.
Just to repeat that - CE399 was NOT the bullet found by Darrell Tomlinson on a stretcher in Parkland Hospital.
To suggest CE399 was planted on a stretcher in Parkland Hospital demonstrates an ignorance of this aspect of the case so staggering as to be complete.
How do we know CE399 was not the bullet found at Parkland?
O P Wright was an ex Dallas Police Chief. A man who knew his guns, knew his ammunition, knew the various types of bullet and calibers.
When Tomlinson handed him the bullet he had found, Wright knew exactly what he was looking at. Being an ex-cop he realized the potential importance of this bullet in terms of the assassination. This bullet was possibly the most important piece of ballistic evidence Wright had ever handled. He set about finding someone in authority to pass this potential evidence to and came across Secret Service agent Johnsen.
When questioned by Josiah Thompson, Wright categorically denied that CE399 was the bullet he handled that day. He didn't say he couldn't remember because he could remember what the bullet was like. He described it as a "hunting slug" with a pointed tip. He even provided Thompson with a similar bullet for comparison:

Around June of '64 Gordon Shanklin, special agent in charge of the Dallas Field Division of the FBI, visited Parkland personally and showed Tomlinson and Wright CE399. Both men refused to identify it as the bullet they handled that day.
Elmer Todd, the man who reportedly received CE399 from Secret Service Chief Rowley showed CE399 to Rowley, Johnsen, Wright and Tomlinson. ALL FOUR MEN refused to identify it as the bullet they handled that day.
The WC Sham 'forgot' to question any of these four men about the bullet found that day. Wright and Johnsen were never asked to testify. Rowley testified at length but was never asked to identify CE399. Unbelievably, Tomlinson, the man who discovered the bullet, was asked to testify before the WC Sham AND WASN'T ASKED A SINGLE QUESTION ABOUT THE BULLET ITSELF!!
He wasn't shown CE399 to identify it as the bullet he found that day.
He wasn't shown a picture of CE399 to identify.
He wasn't even asked to describe the bullet.As astonishing as it may seem, CE399 was still admitted into evidence by the WC Sham even though nobody had identified it as such!How does that work?
CE399 miraculously appears in the chain of evidence with Elmer Todd.
How? How does a bullet apparently fired from the assassination weapon, show up out of nowhere?
LNers believe that just because they accept that CE399 was the bullet Tomlinson found at Parkland, they have somehow side-stepped all the issues raised in this post.
BUT THEY HAVE NOT.
It isn't up to CTers to explain where CE399 came from.
It's up to LNers to explain where it came from in light of the mass of evidence demonstrating that CE399 was NOT the bullet found in Parkland Hospital.
It will be interesting to see which LNers are brave enough to tackle this thorny issue because it is a real problem for their overall theory and most LNers vanish when presented with facts that upset their pet theory.
