They refused to identify it after seven months, or, given the fact that they'd failed to put their initials on it, were unable to identify it after seven months?
PS Take some deep breaths.
In through the nose, out through the mouth . . .

Well done Tom, that's right, they did refuse to identify CE399 as the bullet they handled that day.
Not one or two of them...ALL FOUR MEN refused to identify CE399 as the bullet they handled that day.
All four, Tom.
They were unable to identify it because it was a different bullet.
Rowley and Johnsen didn't put their initials on CE399 because they handled a different bullet that day.
Wright categorically denied that CE399 was the bullet he handled that day.
He received a pointed "hunting slug" from Tomlinson and he gave that bullet to Johnsen.
The WC Sham knew not to question any of these men about CE399, so they didn't.
Even Darrell Tomlinson - the man who discovered the bullet in Parkland - was not asked to identify the bullet when he gave testimony. Let that sink in, Tom.
In fact, he wasn't asked a single question about the bullet itself - the man who discovered this absolutely key piece of evidence for the Sham's fantasy.
Don't forget that CE399 was held up as the key to the Single Bullet Theory. It is one of the most important pieces of evidence in this case as far as the WC's story is concerned.
Yet this fundamental piece of evidence was entered into evidence without a single person identifying it as the bullet that was found in Parkland.
How was that possible Tom?
Why wasn't this questioned by the Sham.
Now that it has been established that CE399 was NOT the bullet found in Parkland, here is a question for the Nutters to answer - where did CE399 come from?
And the answer has nothing to do with missing initials.
