(1) This report is an unclassified version of a classified Report of Investigation of the same title, issued by the Inspector General on April 27, 1998. Classified information that discloses CIA employees undercover and persons who had an intelligence relationship with CIA has been deleted, as has law enforcement information that discloses specific informant relationships. In addition, the names of certain other persons mentioned or discussed in the classified report have been deleted from this version because public disclosure is not clearly authorized under the Privacy Act, 5 U.S.C. §552a, and the Office of Inspector General (OIG) statement of routine uses for information in OIG's system of records governed by the Privacy Act. In such cases, the deleted name has been replaced with a generic descriptor, such as "a U.S. citizen." Where deletions have been made, the unclassified text is as close as possible to the original classified text.
