This is yet another blundering post in which you have (1) merely paraphrased claims you've read on pro-WC websites and (2) ignored documented facts that contradict those claims.
For starters, you don't even understand the nature of the mismatch between the shells found at the scene and the bullets allegedly removed from Tippit's body. The four shells found at the scene were
two Winchester-Western shells and
two Remington-Peters shells, but the four bullets that were allegedly removed from Tippit were
three Winchester-Western bullets and one Remington-Peters bullet. We're not talking about a failure to "ballistically match" the shells and the bullets with Oswald's revolver, but about the fact that the wrong number of Winchester-Western bullets was found in Tippit's body and the wrong number of Remington-Peters bullets was found in Tippit's body, if we assume the bullets came from the shells found at the scene (and this is not to mention the problems with the chain of evidence of the four bullets supposedly removed from Tippit's body).
Of course, you say nothing about the fact that
not one of the four shells entered into evidence had Sergeant W. E. Barnes' or Patrolman J. M. Poe's initials on it, even though both men said they marked two of the shells. So, umm, were they
both "mistaken" about having marked two of the shells, even though they were ordered to mark the shells? Their marks did not appear on the shells entered into evidence because those shells were not the same shells found at the crime scene but were later switched with the original shells, rendering the striation and primer-mark "evidence" as not only worthless but as proof of fraud.
This brings us to another fact that you have ignored: the fact that the shells found at the scene were originally identified as .38 automatic shells, which are marked ".38 AUTO" on the bottom. This is why the first police radio broadcast on the suspect said "the suspect is armed with an automatic .38." The police officer who initially identified the four shells at the scene as .38 AUTO shells was Sergeant Gerald Hill, an 8-year veteran of the Dallas police force and a military veteran who had served in the Korean War. In a 1986 interview, Hill said he knew the shells were .38-caliber automatic shells because he picked up one of them and examined it, and he added that he looked on the bottom of the shell. This is significant because, as mentioned, .38 automatic shells are marked ".38 AUTO" on the bottom. Go read any ballistic handbook and it will tell you it is easy to distinguish between .38 AUTO shells and revolver shells.
Your claims about the eyewitness identifications and the jacket found at the scene were refuted decades ago. I'm certain you haven't read Greg Doudna's ground-breaking research on the jacket.
For readers who want to get a better idea of the flimsy, fraudulent nature of the case against Oswald in the Tippit shooting, I recommend my article
"Did Oswald Shoot Tippit? A Review of Dale Myers' Book With Malice. I provide a good summary of the problems with the case against Oswald in the Tippit murder in my article
"Faulty Evidence: Problems with the Case Against Lee Harvey Oswald" .
People who read either or both of my articles after reading your OP are going to see that you either don't know about or have purposely ignored numerous facts that contradict your claims about the Tippit shooting.
