You don't seem to understand the meaning of the word "repeat". Here's your original statement:
You have offered to prove that the single bullet theory is not true. This is not the same as casting reasonable doubt on the evidence supporting the single bullet theory; it is in fact a far higher burden of proof that you have chosen to assume. Please stop, therefore, avoiding the issue by repeating your personal opinion that CE399 was misidentified, and present your convincing evidence that it is impossible for a single bullet fired by Oswald to have inflicted the known wounds of both Kennedy and Connally.

You're right, I can't prove that no evidence of something means its not true. I'm not interested in getting into squabble with you or arguing about arguing, posters motives or anything like that. If we genuinely want to talk about the SBT rather than win an argument, lets change tack slightly. I guess it would be best if we stuck to discussing what evidence there is to believe CE399 was either the bullet found at Parkland or was fired at Kennedy. Lets do this in a series of for and against arguments. I will post the against, obviously.
Against - the witnesses
Nathan Pool, Darrell Tomlinson and OP Wright are the 3 men involved with the discovery of the bullet at Parkland. Their description of the bullet they found was as follows.
Hospital employees Nathan Pool and Darrel Tomlinson are the 2 men who actually found the bullet. Pool told the HSCA in 1977 it was "long, pointed and smooth". Darrell Tomlinson,told Josiah Thompson in his book 6 seconds in Dallas in 1966 the bullet was a hunting round. Tomlinson gave the bullet to OP Wright, the personnel manager. He not only told Thompson it was a point nosed hunting round -"That bullet had a pointed tip", but produced a similar bullet to the one he saw at Parkland, which is pictured in the book. Its an entirely different type of bullet to CE399.

Neither of these 3 men, or the FBI agents who also handled the bullet that day could ever identify CE399 as the bullet they saw at Parkland as shown by these suppressed FBI memos not shown to the Warren Commuision (no cover up eh?)

There was however, an FBI memo to the Warren Commision that stated FBI agent Bardwell Odum interviewed Wright and Tomlinson and they told him CE399 "appears to be the same" as the bullet they found. Unfortunetly, this seems to be a lie. Bardwell Odum was asked about this incident and he replied:
“I didn’t show it [#399] to anybody at Parkland. I didn’t have any bullet … I don’t think I ever saw it even.”
Could his memory be playing tricks after all these years? Well the FBI report detailing the interview appears to have never existed, its not in the national archives, and despite the reports been numbered consecutively, there are no gaps where it once might have existed.

I guess we should for now, probably discard John Hunts apperent evidence that Agent Elmer Todd's initials don't appear on the bullet in evidence today as CE399 until it can be fully confirmed, but if true would appear to be further evidence against the Parkland bullet been CE399.
So, in terms of witnesses and identification, there is no evidence extant that CE399 was the bullet found at Parkland, and some evidence that it was not.
