The Sixth Floor Museum receives over 300,000 visitors annually. It presents the Warren Commission's conclusions as its organizing framework. Three categories of documented evidence never make it into the exhibits.
The Sixth Floor Museum at Dealey Plaza opened in 1989 with a straightforward institutional purpose: preserve and interpret the site where President Kennedy was assassinated. Over 35 years, it has become Dallas's dominant JFK institution — two million visitors annually, $22+ admission, and a curatorial posture that validates the Warren Commission's lone-gunman narrative while treating contrary evidence as a fringe curiosity.
This is a documented pattern, not an opinion. The museum receives its visitors before they have access to the full record. By the time those visitors encounter what the HSCA concluded, what the 2025 declassifications revealed, or what 70+ Dealey Plaza witnesses actually said, the narrative frame has already been set.
DealeyTruth exists to present that full record. The three exhibits below represent the most significant categories of evidence the Sixth Floor Museum has systematically excluded or minimized. Each is sourced from official government documents, sworn congressional testimony, and declassified records — not speculation.
Each of these findings comes from official government sources — not alternative researchers. The Sixth Floor Museum has access to all of it. They've chosen not to feature it.
The most thorough federal investigation of the assassination concluded Kennedy was "probably assassinated as a result of a conspiracy" — based on acoustic evidence, forensic pathology, and grassy knoll testimony from multiple witnesses. This is the only official U.S. government conclusion on record. The Sixth Floor treats it as a footnote.
"The committee believes, on the basis of the evidence available to it, that President John F. Kennedy was probably assassinated as a result of a conspiracy."
HSCA findings presented as secondary to the Warren Commission. Conspiracy conclusion framed with passive language. Equal exhibit space is not given.
~80,000 pages released including nine fully declassified James Angleton memos, the complete Mexico City Station History (CIA surveillance of Oswald's embassy visits), and documents showing 1,500+ CIA agents embedded as "diplomats" in U.S. embassies across the Kennedy era. The Sixth Floor Museum has no mention of any of it.
"The most positive news on JFK declassification since the 1990s... The Angleton memos are the most important collection in the release."
No exhibit updates. No reference to Angleton, Mexico City Station, or CIA compartmentalization. Permanent exhibits were last substantively updated years before this release.
Over 70 Dealey Plaza witnesses reported shots from multiple directions, including the grassy knoll. The dictabelt acoustic analysis identified evidence of a fourth shot inconsistent with a single shooter. Forensic pathologists including Cyril Wecht documented head-motion analysis inconsistent with a rear-only trajectory. The Sixth Floor labels all of this "conspiracy theory."
HSCA acoustic evidence: "There was a high probability that two gunmen fired at President Kennedy" — dictabelt recording analysis, 1979.
Single-bullet theory presented as established fact. Zapruder film shown with most graphic frames omitted. Witness testimony reduced to background context.
The House Select Committee on Assassinations was convened in 1976 and delivered its final report in 1979. It is the largest, most resource-intensive federal investigation of the assassination since the Warren Commission — and it reached the opposite conclusion.
"The committee believes, on the basis of the evidence available to it, that President John F. Kennedy was probably assassinated as a result of a conspiracy."
— HSCA Final Report, 1979 (Vol. I, p. 1)The HSCA's conclusion was based on specific evidentiary findings — not speculation. The committee's acoustic panel analyzed a dictabelt recording from a Dallas Police Department motorcycle radio and identified acoustic signatures consistent with four shots, including one from the direction of the grassy knoll.
The HSCA's 26-volume report is the most thorough federal investigation of the assassination on record. It is publicly available. Every major academic institution with a JFK collection holds copies. The Sixth Floor Museum is a 15-minute drive from the National Archives Southwest Region, which maintains related records.
The Warren Commission's lone-gunman conclusion receives the primary narrative frame. The HSCA's "probable conspiracy" finding is presented alongside "various conspiracy theories" without distinguishing the committee's official conclusion from fringe speculation. Visitor reviews from 2016 through 2023 consistently note the imbalance.
On March 18, 2025, the National Archives released approximately 80,000 pages of previously classified or heavily redacted CIA documents under Executive Order 14176. This is the most significant JFK records release since the 1990s — and it covers material directly relevant to any serious examination of the assassination.
"The Angleton memos are the most important collection in this release... This is the most positive news on JFK declassification since the 1990s."
— Jefferson Morley, Mary Ferrell Foundation VP & JFK Records Expert, March 2025These documents do not "solve" the assassination. What they do is establish — through primary sources — the operational capacity and institutional incentive for the kind of information control that investigators have long hypothesized. That is not speculation. It is documented fact, now publicly available.
No reference to the March 2025 declassifications. No mention of the Angleton memos or Mexico City Station History. The CIA is presented as a passive participant in post-assassination investigation — not as an active operational actor with documented capacity for information control.
The Mary Ferrell Foundation's Dealey Plaza Witness Database documents testimony from over 70 witnesses who reported hearing shots from more than one direction, including from the grassy knoll area north and west of the motorcade. These witnesses include police officers, Secret Service agents, journalists, and bystanders — people trained to observe.
The forensic record is not unanimous. There are credentialed researchers who support the Warren Commission's findings and credentialed researchers who contest them. That is precisely the point: the evidence is genuinely contested, and an honest institution presents that contestation rather than resolving it in advance for the visitor.
The single-bullet theory is presented as established fact, not disputed hypothesis. Witness testimony reporting grassy knoll shots is categorized under "conspiracy theories" rather than "alternative evidence." Forensic pathology dissent is absent or marginalized. The museum's own visitor reviews note — repeatedly, across years — that alternative perspectives receive unequal treatment.
Everything described above is publicly available. These are the archives and institutions that have preserved and digitized the documentary record.
This evidence exists. It's in official government archives, congressional reports, and declassified records. It deserves an institution willing to present it. DealeyTruth is building that institution — near Dealey Plaza, in Dallas.
