On November 22, 1963, President John F. Kennedy was assassinated in Dallas, Texas. This tragic event shook the nation and led to the creation of the Warren Commission, tasked with investigating the circumstances surrounding the assassination. However, the Commission’s work was hampered by a significant blind spot: the compartmentalization of information within intelligence agencies. This article explores how this compartmentalization affected the investigation and potentially left important questions unanswered.

The Birth of the Warren Commission

After President Kennedy’s assassination, many Americans questioned how such a tragedy could occur despite the vast U.S. intelligence apparatus. President Lyndon B. Johnson established the Warren Commission on November 29, 1963 to address public concern and ensure a thorough investigation.

The Commission’s goal was to conduct an independent investigation into the assassination. It aimed to go beyond simply accepting reports from federal or state agencies, recognizing the need to address the numerous rumors and theories circulating at the time.

Reliance on Intelligence Agencies

Despite its mandate for independence, the Warren Commission heavily relied on intelligence agencies, particularly the FBI, for its investigation. The Commission received many reports from various agencies, with the FBI providing the largest number.

The FBI’s Central Role

The FBI was the primary source of information for the Warren Commission. The Bureau forwarded a five-volume report summarizing its initial investigation and later provided additional field investigation reports at the Commission’s request.

Dependence on Agency Information

The Warren Commission’s reliance on intelligence agencies went beyond just receiving reports. With minor exceptions, the entire body of factual material used by the Commission came from the intelligence community, primarily the FBI. This dependence meant the Commission’s findings were largely based on information filtered through these agencies.

The Problem of Compartmentalization

While the Warren Commission relied heavily on intelligence agencies, these agencies themselves dealt with internal compartmentalization of information, which created significant blind spots in the investigation.

CIA’s Compartmentalized Knowledge

One of the most striking examples of compartmentalization was within the CIA. Many CIA officials involved in the Kennedy assassination investigation were unaware of the agency’s assassination plots against Cuban leader Fidel Castro.

The AMLASH Operation

A key piece of information that remained hidden due to compartmentalization was the CIA’s AMLASH operation. This operation, which involved plotting with a Cuban official to assassinate Castro, was ongoing at the time of Kennedy’s assassination. However, the CIA officers liaising with the Warren Commission were unaware of this operation.

FBI’s Limited Investigation

The FBI’s investigation was primarily focused on Lee Harvey Oswald, the man accused of assassinating President Kennedy. As one FBI supervisor described it, “it was an investigation of Lee Harvey Oswald, the man”. This narrow focus meant that other potential leads, particularly those involving Cuba, were not thoroughly explored.

Missed Opportunities

The compartmentalization of information led to several missed opportunities in the investigation:

1. The Castro Warning

In September 1963, just months before the assassination, Cuban leader Fidel Castro gave an interview warning that U.S. leaders would be in danger if they aided attempts to eliminate Cuban leaders . U.S. intelligence agencies largely overlooked this warning at the time.

2. The Cubana Airlines Flight

On December 1, 1963, the CIA received information about a Cuban Airlines flight from Mexico City to Cuba that was delayed for five hours, waiting for an unidentified passenger . This lead, which could have been significant, was not thoroughly investigated.

3. Cuban Exile Groups

The FBI had information about Cuban exile groups that may have been relevant to the investigation. However, this information was not fully shared with the Warren Commission.

The Impact on the Investigation

The compartmentalization of information within and between intelligence agencies had a significant impact on the Warren Commission’s investigation:

Limited Scope

Because the Commission was unaware of certain CIA operations, particularly those involving Cuba, it couldn’t fully explore potential connections between these operations and the assassination.

Incomplete Picture

The Commission’s heavy reliance on the FBI, combined with the FBI’s narrow focus on Oswald, meant that other potential leads and theories were not thoroughly investigated.

Missed Connections

Some officials who knew about both the assassination investigation and CIA operations, like AMLASH, later admitted that it would have been logical to consider a potential connection. However, due to compartmentalization, this connection was not explored at the time.

Long-Term Consequences

The effects of compartmentalization continued to impact the investigation even years after the Warren Commission concluded its work:

1967 Revelations

In 1967, allegations surfaced about potential Cuban involvement in the assassination. These allegations were based on information about U.S. attempts to assassinate Castro. However, because of the earlier compartmentalization, these leads were not thoroughly investigated.

Ongoing Questions

The compartmentalization of information has left many questions unanswered, contributing to ongoing debates and conspiracy theories about the Kennedy assassination.

Lessons for Future Investigations

The Warren Commission’s experience highlights several important lessons for intelligence agencies and investigative bodies:

  1. The danger of over-compartmentalization within agencies
  2. The need for better information sharing between agencies
  3. The importance of a genuinely independent investigation that can access all relevant information
  4. The value of considering all potential leads, even those that seem unlikely at first glance

The Lingering Shadow of Compartmentalization

The compartmentalization within intelligence agencies cast a long shadow over the Warren Commission’s investigation. It created blind spots that prevented a truly comprehensive examination of the events surrounding President Kennedy’s assassination.

While the Commission and the intelligence agencies involved undoubtedly worked hard to uncover the truth, the structural barriers created by compartmentalization hindered their efforts. This case is a stark reminder of the challenges faced in balancing the need for secrecy in intelligence operations with the public’s right to a thorough and transparent investigation of such a significant event in American history.

As we continue to grapple with the legacy of the Kennedy assassination and the Warren Commission, it’s crucial to remember the impact of compartmentalization. By understanding these past challenges, we can work towards creating more effective and transparent investigative processes for the future, ensuring that institutional blind spots do not hamper the pursuit of truth.
