As alleged "Nazi war criminal" John Demjanjuk's chief researcher and archivist, as a coplaintiff in an ongoing civil lawsuit in Washington against the Justice Department's official "Nazi-hunting" authority, the Office of Special Investigations, and as an American who has witnessed the media and educational extravaganza that purports to be a fair trial, I wish to rebuke former Office of Special Investigations director Allan Ryan's hallucinations and self-serving platitudes {"The Questioning of Israeli Judges," letters, Sept. 28}.

Mr. Ryan says that "the eyes of the world are on them {the Israeli three-judge panel} and on the integrity of the Israeli judicial system." If the Demjanjuk trial were indeed fair, then the judicial authorities would have provided financial assistance for an indigent defendant, as they did in the Eichmann proceeding. They would not have begged Soviet authorities for "incriminating evidence" after the fact of extradition. They would not have kept Mr. Demjanjuk in solitary confinement for seven months before proffering criminal charges, and they certainly would not have permitted a revolving-door procession of politicians to make inflammatory and premature statements regarding Mr. Demjanjuk's alleged guilt.

Mr. Ryan's other assertion -- that the judges' meticulous attention to the evidence did not unduly disrupt the orderly flow of examination -- is incorrect, and is answered by extracts from a letter in my possession written by a defense witness, document examiner Edna Robertson:

"I was not oblivious to what was going on with me. My testimony was damaging to their case and I knew I would receive harsh cross examination but I never expected to be abused by the judges and the prosecution. Gross abuses were the intimidating last chances to revoke my testimony; being required to comment as an expert on documents which I had never seen before; being cross-examined by the judges and prosecution; and being cross-examined outside my field of expertise. Of course {defense counsel} objected but they were overruled and the judges and prosecution continued the abuse. . . . I sincerely hope that conditions will improve for the rest of the trial."

If The Post spent more time examining the genuine issues surrounding the Demjanjuk tragedy, such as OSI's withholding of exculpatory evidence from both the Israelis and the defense, rather than glamorizing the sharks feeding on Mr. Demjanjuk's misfortune, there would never have been a need to write this letter.
