It depends on how reliable and accurate O.P. Wright's memory was in 1967. It also depends on how reliable and accurate Josiah Thompson's account of his interaction with Wright was.
What I am saying is that real evidence fits together and makes sense.
I am not sure how "unequivocal" he was in 1966. Thompson says "he seemed quite prepared to stick by his story" that the bullet he gave to Johnsen had a pointed tip. (Six Seconds in Dallas, p. 175). I am also not sure how reliable we can expect Wright's memory of this to be 3 years after the fact. It wasn't very good 6 months after the fact (CE2011) because he couldn't recognize it when asked. But he also did not deny it like Thompson would have us believe he did in November 1966.
Having said that, it is somewhat surprising that Arlen Specter did not show Tomlinson the bullet CE399 or at least a photo of it when he examined him under oath in March 1964 (6 H 128). But I don't see any reason to think that Specter was trying to hide anything. The point in speaking with Tomlinson was not to identify CE399 but to identify where the bullet that he found came from.
Secret Service agents are trained as law enforcement officers or investigators? How do we know that? It seems that no one wanted to take responsibility for it and kept passing it off until it eventually reached Todd who then turned it over to the FBI.
I actually agree with you on this. CE399 did not go through JBC. CE399 was the first shot. There is no clear evidence as to where it went after passing through JFK. JBC said he was hit in the back on the second shot. He never felt the thigh shot. It would not be surprising if the bullet stuck in his left thigh and came out of his thigh when they put him on the stretcher. It might have been spinning rapidly after exiting JFK's neck (it came out under his tie), struck JBC's thigh and kept going - landing somehow on the outside of his clothing. It is not something that can be determined because we don't have evidence of anything except the general trajectory.
It wasn't very good 6 months after the fact (CE2011) because he couldn't recognize it when asked. But he also did not deny it like Thompson would have us believe he did in November 1966. Wrong, he didn't recognize it because he was never shown the bullet. S.A. Odum who, according to CE2011, is supposed to have shown CE399 to Tomlinson and Wright denied that he did so.
The point in speaking with Tomlinson was not to identify CE399 but to identify where the bullet that he found came from.What bullet would that be? In order to identify where Tomlinson found "the bullet" one first has to establish which bullet one is talking about? And why not simply to both things? Identify the bullet and the location? During Humes' testimony, didn't Specter introduce CE399 into evidence
subject to later proof, this is the missile which has been taken from the stretcher which the evidence now indicates was the stretcher occupied by Governor Connally?
Tomlinson was the only person who could identify the bullet and the location where he found it. IMO Specter did noy ask him a single question about the bullet because he could not risk Tomlinson saying on the record that the bullet shown to him wasn't the one he had found.
