“How the palmprint can be accepted as evidence is truly baffling.”
Because the FBI identified the palmprint, CE 2637, taken from LHO's rifle as having the irregularities associated with the barrel of the rifle and these irregularities from the barrel were present on the palmprint taken by Day.
CE 2637 proved the palmprint was taken from the barrel of the rifle.
If you'd bothered to read my post Jack, I agree that the print was lifted from the barrel of the rifle and that is why the irregularities of the rifle barrel are on the palmprint in evidence.
The part you would like to ignore is that, according to FBI agent Drain, it was the opinion of the FBI fingerprint experts that it was Day who had put the print on the rifle barrel
before it was lifted.
So your so called proof doesn't really stack up to what you imagine it does.
And, as I say in the rest of the lengthy post (that you haven't mentioned so I assume you agree with it), the mystery of why there was no print on the barrel of the rifle when it got to the FBI is solved. The mystery of why there was no sign that the barrel was even processed for prints is solved. The mystery of why Day never took a photo of the print before attempting to lift it is solved. The mystery of why Day never handed the print to the FBI along with the rest of the evidence is solved.
Unless, of course, you have different solutions to these mysteries.
And I'm glad you agree that if Day had indeed lifted Oswald's palmprint from the barrel it would have been considered the most important piece of evidence collected that day.
The mystery as to why this most important piece of evidence was treated as if it were irrelevant is also solved.
Day was the fingerprint expert for the Dallas Police Department.
The FBI thought he'd faked the print.
Do you really think he wouldn't have realised he needed to make it look as though the palmprint actually came from the barrel of the rifle?
Do you really think he wouldn't know how to do it?
Do you have any kind of rational, credible explanation for the "mysteries" surrounding the palmprint.
If so, please share.
