Iran-Contra Investigation: PROFS Computer Message System Backup Tapes Inventory

SUMMARY

During the Iran-Contra investigation, backup tapes from the National Security Council's (NSC) PROFS (Professional Office System) computer messaging system became crucial evidence. PROFS, an IBM product, included an email component known as PROFS Notes. Despite attempts by some officials, such as Oliver North, to delete their correspondence, the system's backup tapes preserved these communications.

Career staff at the White House Communications Agency reportedly ordered the November 1986 backup tapes of the email system to be saved rather than recycled, an action that proved critical for investigators. These tapes were subsequently used by the FBI and the Tower Commission to reconstruct events related to the Iran-Contra scandal. The PROFS notes were instrumental in the Tower Commission's report issued in February 1987, which reprinted hundreds of these exchanges. However, a comprehensive, official inventory list of all PROFS backup tapes recovered and utilized by investigators during the Iran-Contra affair does not appear to be readily available in the provided sources.

STRONGEST CASE FOR

The existence and utilization of PROFS backup tapes were critical to uncovering the Iran-Contra affair. These tapes contained electronic mail messages, including those of Oliver North, which investigators like the FBI and the Tower Commission used to reconstruct events. The fact that White House Communications Agency staff actively saved these tapes in November 1986, preventing their usual recycling, suggests a conscious effort that preserved vital evidence. The declassified use of these tapes in official reports underscores their evidentiary value and reliability, indicating that a formal inventory must have been maintained by the investigative bodies.

STRONGEST CASE AGAINST

While the PROFS tapes were undoubtedly important, the challenge lies in locating a specific, comprehensive inventory list that details every tape recovered. The information available generally confirms the use of 'backup tapes' without specifying quantities, dates beyond '1986 and 1987,' or a precise catalog of their contents. The focus in public reporting has been on the incriminating information found, rather than on the meticulous archival process. Without a public, detailed inventory, it's difficult to ascertain if all relevant tapes were indeed recovered or if certain periods or individuals' communications are missing from the known record.
