It is utterly amazing to me that CTs insist on assuming that the explanations provided by police officers are not to be trusted unless every conceivable means by which the evidence could be falsified is considered and disproved.
In the case of the letter, which was shown by handwriting experts to have been written by Oswald, any scenario in which it could have been planted leads to absurdities. How on Earth would anyone have been involved in planting something that could not have been made by anyone other than Oswald and have Marina identify it as such?
The fact that it was found accidentally strongly supports Marina's evidence that it is authentic. It was deliberately hidden, as Marina later admitted, in a place where Oswald would not likely find it. Marina told Oswald that she would go to the police with it if Oswald ever reneged on his promise.
It is utterly amazing to me that CTs insist on assuming that the explanations provided by police officers are not to be trustedEven more amazing would be to assume that police officers always tell the truth and never purposely lie.
If and when a police officer finds a piece of evidence, adheres to the chain of custody requirements, places or has placed the evidence into the evidence room as quickly as possible and makes mention of the evidence he found in his report, there would indeed be no apparant reason to distrust that police officer's explanations. But that wouldn't prevent any defense lawyer to explore all options to discredit that officer.
However, when a police officer claims, long after the fact and the death of the suspect, that he found a piece of evidence, which he did not mention in any contemporary report and for which there is no chain of custody, then it is reasonable to question the trustworthiness of that officer.
In the case of the letter, which was shown by handwriting experts to have been written by Oswald,No. That's a misrepresentation. An expert saying that there are similarities with Oswald's writing is not the same as saying that Oswald wrote it. With this in mind it is fair to say that the experts did not agree about the letter being written by Oswald
How on Earth would anyone have been involved in planting something that could not have been made by anyone other than Oswald How on Earth did you reach that conclusion?
and have Marina identify it as such?It doesn't matter much what Marina identified if she wasn't a reliable witness. The record is clear that Marina was anything but reliable and may well have had her own agenda after Lee's death. She hired a business manager shortly after the event. What kind of witness does that?
The fact that it was found accidentally strongly supports Marina's evidence that it is authentic.What makes you think it was accidentally found?
It was deliberately hidden, as Marina later admitted, in a place where Oswald would not likely find it. Marina told Oswald that she would go to the police with it if Oswald ever reneged on his promise. Nice story... for which your only source is Marina.
