Comments to Karman's points:
The Shelepin’s note was hand-written on a blank sheet of paper without letterhead and that is unique for an official KGB document.
Prove it. How many KGB documents have you studied?
But if we buy it then the secrecy code of the document is wrong: it has a lower secrecy code: “совершенно секретно” but the top secrecy code in the Soviet Union starting from 20th till the 90th of the last century was: “особая папка”.
Source?
2. The text of the note says that the KGB files keep the official records of imprisoned and interned Polish officers, gendarmes, police officers and colonists, landlords etc. But according to a document published together with other Katyn documents all records for prisoners of Starobelsky camp were shredded. So Shelepin could not say that they are kept in KGB.
The records that were in the camp. And then, not all of them, as I have shown. And who is to say that there were no copies in the central agency?
3. Shelepin’s note stated that the execution of prisoners and internees was performed on the basis of the Decision of Central Committee of the Communist Party of the Soviet Union. It is supposed that when Shelepin was writing his note he had some documents in front of him he used to compile this note. That is strange that he used anachronism in the name of the Communist Party. In 1940 it was not called CPSU but VKP(b) – All-Soviet Communist Party (Bolsheviks).
I have provided many examples of such anachronisms, and I have several more of them.
4. The note says that all prisoners and internees were sentenced to death on the basis of «учетных дел» (filing records) initiated on them in camps in 1940. But that confronts the information contained in the extract from the Minutes of Politburo meeting which says that the Polish officers were executed on the basis of notes (справка) issued by the heads of camps and criminal cases «уголовное дело» (but not filing records). In accordance with the Beria’s memorandum Beria proposed to execute those officers who participated in counter-revolutionary organizations. And those were definitely kept in prisons and camps on the basis of criminal cases but not common filing records for POW and internees. And those criminal cases were reviewed by “troika” that sentenced them to death.
Well, Shelepin might have made a clerical mistake. Boo hoo!
5. Shelepin used the wrong name of the Authorized Special Committee for Investigation of the massacre in Katyn and used wrong name of the state authorities initiated the work of that Committee.
He omitted a word or two, IIRC. Certainly not a mistake that indicates a forgery - not even a corroborating piece of evidence for the forgery hypothesis.
6. Signing the document “Shelepin” writes: Chairman of the Committee of the State Security of the Council of Ministers of USSR. («Председатель Комитета Государственной Безопасности при Совете Министров СССР»). According to the rules of the Russian literate language only the first word in the name of an organization is written with a capital letter. There are known none of the documents where all words of the name KGB were written with capital letters.
Oh gee, back to square one: how many KGB documents have you examined in your life?
Shelepin never did it in the rest of his letters.
Wow, you have seen all of Shelepin's letters? Even those still classified? Do you work in FSB?
Seriously, according to Shelepin himself he didn't write the letter by himself, there was a special man at KGB for such cases.
7. Shelepin himself always denied that he ever wrote this note. He always said that the first time he learnt from newspapers about the Katyn case.
It's Mukhin's bald-faced lie, and I think I have even discussed it on this board.
8. Nobody has ever seen the originals of those documents.
Another lie.
