23 December 1946 MEMORANDUM FOR MR. DOUGLAS L. WALDORF Subject: Organization of Investigative Work Relative to Witnesses Subpoened by the Accused. It occurred to me that it would be well to set forth in writing the substance of our previous conversations relating to this matter. Although additional suggestions will be made from time to time, the following statement is about all we can agree to at the present: 1)Issue directives to the Japanese government for production of biographical data relating to each witness. 2)Make examination of documents in IPS Document Center for information relating to each witness. 3)Examine petitions filed by the accused for subpoenaing of witnesses and transcript of the evidence for the purpose of determining as nearly as may be the purpose for which each witness is being called. For instance, if Miss Culverwell’s analyses of testimony regarding Matsui is examined you can find at a glance the pages in the transcript dealing with testimony against Matsui. Reference to the testimony will likely give an indication as to the purpose of calling certain of his witnesses. 4)Present the biological data and a statement regarding the purpose of subpoenaing each witness to the attorney handling the case against the accused who seeks the production of the witness for the purpose of discussion and determination of the next investigative action to be taken. I enclose a statement of the attorneys assigned to the various accused. ___________________ Frank S. Tavenner, Jr.
