The implication suggests that something sinister could have happened with this item. No credible evidence that it did happen. Are you claiming that something sinister DID happen?
I made no such claim. I am merely stating that the possibility that it did happen can not be ruled out.
In the WC case against Oswald there a plenty of claims for which there either is no credible evidence, or - even worse - credible evidence that does not support the claim is simply dismissed. Yet, you accept the case against Oswald. Why the double standard?
As to the item discussed, there also is no credible evidence that it didn't happen. Absence of evidence is not evidence of absence. Given the multitude of instances where there has been questional handling of physical evidence, a circumstantial case of evidence manipulation can be made, but we have already established that you are not interested in that and just call it "conjecture and innuendo"
