American intelligence agencies spied on the late South African leader Nelson Mandela during his historic 1990 visit to the United States shortly after his release from a 27-year sentence for anti-apartheid activism.

That revelation is but one of the findings from a batch of documents released by the FBI in response to a Freedom of Information Act (FOIA) lawsuit filed by Massachusetts Institute of Technology doctoral candidate Ryan Shapiro.

The 38-year-old historian sued the FBI, National Security Agency, Defense Intelligence Agency and the Central Intelligence Agency in March for failing to fulfill FOIA requests for records about the spy agenciesโ€™ alleged involvement in Mandelaโ€™s 1962 arrest and his placement on the U.S. terror watch list until 2008, among other things.

โ€œThough itโ€™s unfortunate it required a lawsuit, Iโ€™m of course pleased the FBI is now complying in part with my FOIA request,โ€ Shapiro told the AFRO. โ€œAs a result, we now have evidence the FBI spied on Mandela while they were supposed to be protecting him.โ€

According to the documents, the FBI developed a confidential informant, referred to as the โ€œsource,โ€ who was at least closely affiliated with Mandelaโ€™s U.S. entourage. That informant provided logistical information, such as places and times where Mandela would be, and political information, such as a prospective meeting with Louis Farrakhan, and the identities and recent travels of African National Congress (ANC) leaders in the U.S. At the time, the ANC was still considered a terrorist organization by the U.S. government.

The FBI documents also revealed that several death threats were made against Mandela during his visit. A particularly disturbing one came in the form of a handwritten letter attached to a Houston Chronicle article about the iconic leaderโ€™s potential visit to the Texas city. It threatened, โ€œRemember John F. Kennedy in Dallas? Bring this Black murderer to Houston and we will give him a welcome that the world will not forget!!!โ€

Shapiro said there were several issues that were not addressed in the hundreds of pages provided by the FBI.

โ€œWhatโ€™s missing from these documents is often as illuminative as whatโ€™s disclosed,โ€ he said. โ€œNot only did the FBI heavily redact and withhold documents, but thereโ€™s virtually no discussion of U.S. intelligence community involvement prior to Mandelaโ€™s 1990 release from prison.

โ€œWorse,โ€ he added, โ€œthe agencies most likely to possess such records, the CIA and NSA, continue their refusal to comply with my FOIA requests. Hopefully the judge will compel these agencies to release their documents, but it shouldnโ€™t take a lawsuit to obtain records from a FOIA request. And itโ€™s an especially sad day when the notoriously anti-FOIA FBI is the agency coming closest to compliance with the requirements of the statute.โ€

Shapiro, a historian who focuses on political functioning of national security and the policing of dissent, said his FOIA requests and follow-up lawsuits were part of his campaign to increase transparency among U.S. government agencies.

โ€œThe democratic process cannot meaningfully function without an informed citizenry, and such a citizenry is impossible without broad public access to information about the operations of government,โ€ he said. โ€œItโ€™s time for the U.S. intelligence community to recognize transparency not as a threat, but rather as an essential component of viable democracy.”
