Who Was William Guy Banister and How Did He Relate to the JFK As.sas.sin.ati.onn?

Guy Banister spent seventeen years in the Federal Bureau of Investigation, longer than almost any agent except the director himself.

During the Second World War he was dispatched to Mexico City, where he entered the German embassy, opened a safe, removed cryptographic material, and left listening devices behind.

The success of that black-bag operation earned him promotion to special agent in charge of the Chicago field office.

He was regarded inside the Bureau as an expert in electronic surveillance and surreptitious entry.

Around 1950 he underwent lengthy brain surgery. Colleagues and family later said the operation left him subject to sudden, violent rages.

He left the Bureau under circumstances that were never fully clarified and accepted an appointment as a senior officer in the New Orleans Police Department, charged by the mayor with cleaning up corruption.

The mayor died shortly afterward in a plane crash in Mexico. Banister’s tenure on the force ended after an incident in which he drew a .357 Magnum in a bar.

He then opened Guy Banister Associates, a private investigative firm that occupied space at 544 Camp Street.

The second floor of the building connected to 531 Lafayette Street and housed a cluster of anti-Castro exile organizations.

Banister’s own office used a filing system modeled on the Dewey Decimal classification employed by J. Edgar Hoover. After Banister’s death the file covers that remained listed headings such as Central Intelligence Agency, ammunition and arms, anti-Soviet underground, Fair Play for Cuba Committee, and Latin America.

His secretary and companion, Delphine Roberts, later stated that Oswald had been given a small office on the third floor and had used the Camp Street address on leaflets he distributed.

Roberts, a Daughter of the American Revolution and active anti-communist, described Banister as still carrying out federal assignments long after he left official payroll.

Banister formed a close working relationship with David Ferrie, the former Eastern Airlines pilot who also occupied space in the building.

Together they participated in the training of Cuban exiles and mercenaries on the north shore of Lake Pontchartrain.

A nearby Schlumberger facility that stored industrial explosives was raided; Banister, Ferrie, and others were arrested for violations of the Neutrality Act after the Kennedy administration ordered an end to unauthorized paramilitary activity against Cuba.

The arrests inflamed local resentment toward the White House. Banister maintained friendships with a circle of hard-line figures that included the exiled Cuban dictator Fulgencio Batista, the suspended General Edwin Walker, and George Lincoln Rockwell of the American Nazi Party.

He and Walker shared an intense hostility toward the Kennedy administration’s handling of the Bay of Pigs and subsequent restrictions on exile operations.

Banister ran unsuccessfully for New Orleans City Council as a Democrat while continuing to compile extensive files on left-wing activity.

When Banister died in 1964, police and other parties moved quickly to secure the contents of his office.

Jim Garrison’s investigators later recovered only the empty file covers whose subject headings indicated an intelligence rather than a domestic-relations caseload.

Delphine Roberts told both the House Select Committee on Assassinations and author Anthony Summers that she had been instructed to protect the files and that Oswald’s presence at the Camp Street address was known to those who worked there.

The physical proximity of the building to Secret Service, Office of Naval Intelligence, and other federal offices in downtown New Orleans added to the density of the setting.

Banister’s combination of Bureau training, local police authority, private-office cover, and documented association with both Ferrie and the Camp Street leaflet operation placed him at a nodal point in the anti-Castro milieu of 1963.

The incomplete survival of his records has left subsequent researchers with a clear outline of the network and an equally clear absence of the detailed contents that once filled the cabinets.

Because nothing says “ordinary private eye” quite like Dewey Decimal files on ballistic missiles and a secretary who insists the federal government never really let him go.
