Rush to Judgment: A Critique of the Warren Commission's Inquiry into the Murders of President John F. Kennedy, Officer J.D. Tippit and Lee Harvey Oswald is a 1966 book by American lawyer Mark Lane.
 It is about the assassination of U.S. President John F. Kennedy and takes issue with the investigatory methods and conclusions of the Warren Commission.
 The book's introduction is by Hugh Trevor-Roper, Regius Professor of History at the University of Oxford.
 Although it was preceded by a few self-published or small press books, "Rush to Judgment" was the first mass-marketed hardcover book to confront the findings of the Warren Commission.
The Trial of Lee Harvey Oswald is a 1964 American film from Larry Buchanan.
 It is the first speculative trial drama to be produced about Lee Harvey Oswald only a few months after the assassination of John F. Kennedy along with the assassination of Lee Harvey Oswald himself.
 The film was made in Dallas, and served as an idea of what the trial would have been like had it occurred, if Oswald hadn't been killed by Jack Ruby.
 In the film, the prosecution asserts Oswald committed the crime for political reasons due to his Marxist beliefs, while Oswald's attorney presents an insanity defense, claiming he suffered from untreated paranoid schizophrenia since adolescence.
 Since the viewer acts as a juror, no verdict is given.
Marina Nikolayevna Oswald Porter (née Prusakova; Russian: Марина Николаевна Прусакова born on July 17, 1941) is the widow of Lee Harvey Oswald, the assassin of U.S. President John F. Kennedy.
 She married Oswald during his temporary defection to the Soviet Union and immigrated to the United States with him.
 She was not implicated in the assassination and remarried two years following Oswald's murder.
In March 1963, Lee Harvey Oswald, using the alias "A. Hidell," purchased by mail order a 6.5×52mm Carcano Model 91/38 infantry rifle (described by the President's Commission on the Assassination of President Kennedy as a "Mannlicher–Carcano" ) rifle with a telescopic sight.
 He also purchased a revolver from a different company, by the same method.
 The Hidell alias was determined from multiple sources to be Oswald.
 It is officially accepted that the rifle was fired by Oswald from the Texas School Book Depository in Dallas, Texas, to assassinate United States President John F. Kennedy as his motorcade drove by on November 22, 1963.
 Photographs of Oswald holding the rifle, a palmprint found upon examination of the rifle, and detective work tracing its sale, all eventually led to Oswald.
 Marina Oswald later testified she was told by Lee that the rifle was also used before in an attempt to assassinate retired U.S. Army General Edwin Walker in Dallas.
Hugh Grant Aynesworth (born August 2, 1931) is an American journalist, investigative reporter, author, and teacher.
 Aynesworth has been reported to have witnessed the assassination of John F. Kennedy in Dealey Plaza, the capture and arrest of Lee Harvey Oswald at the Texas Theater, and the shooting of Lee Harvey Oswald by Jack Ruby in the basement of the Dallas Police Headquarters.
 In a 1976 "Texas Monthly" article, William Broyles, Jr. described Aynesworth as "one of the most respected authorities on the assassination of John F. Kennedy".
Ruth Hyde Paine (born September 3, 1932) was a friend of Marina Oswald, who was living with her at the time of the JFK assassination.
 According to five government investigations, Lee Harvey Oswald stored the 6.5 mm caliber Carcano rifle that he used to assassinate U.S. President John F. Kennedy in Ruth Paine's garage, unbeknownst to her and her husband, Michael Paine.
Carcano is the frequently used name for a series of Italian bolt-action, magazine-fed, repeating military rifles and carbines. Introduced in 1891, this rifle was chambered for the rimless 6.5×52mm Carcano cartridge ("Cartuccia Modello 1895").
 It was developed by the chief technician Salvatore Carcano at the Turin Army Arsenal in 1890 and called the Modello (model) 91 or simply M91.
 Successively replacing the previous Vetterli-Vitali rifles and carbines in 10.35×47mmR, it was produced from 1892 to 1945.
 The M91 was used in both rifle ("fucile") and shorter-barreled carbine ("moschetto") form by most Italian troops during the First World War and by Italian and some German forces during the Second World War.
 The rifle was also used during the Winter War by Finland, and again by regular and irregular forces in Syria, Libya, Tunisia, and Algeria during various postwar conflicts in those countries.
The President's Commission on the Assassination of President Kennedy, known unofficially as the Warren Commission, was established by President Lyndon B. Johnson through Executive Order on November 29, 1963 to investigate the assassination of United States President John F. Kennedy that had taken place on November 22, 1963.
 The U.S. Congress passed Senate Joint Resolution 137 authorizing the Presidential appointed Commission to report on the assassination of President John F. Kennedy, mandating the attendance and testimony of witnesses and the production of evidence.
 Its 888-page final report was presented to President Johnson on September 24, 1964 and made public three days later.
 It concluded that President Kennedy was assassinated by Lee Harvey Oswald and that Oswald acted entirely alone.
 It also concluded that Jack Ruby also acted alone when he killed Oswald two days later.
 The Commission's findings have proven controversial and have been both challenged and supported by later studies.
The Trial of Lee Harvey Oswald is an American two-part television film shown on ABC-TV in September 1977.
 The film starred Ben Gazzara, Lorne Greene and John Pleshette in the title role.
 It is an example of alternative history.
 The hypothesis is what might have happened if Lee Harvey Oswald had not been killed by Jack Ruby and had stood trial for the murder of President John F. Kennedy.
David William Ferrie (March 28, 1918 – February 22, 1967) was an American pilot who was alleged by New Orleans District Attorney Jim Garrison to have been involved in a conspiracy to assassinate President John F. Kennedy.
 Garrison also alleged that Ferrie knew Lee Harvey Oswald.
 Ferrie denied any involvement in a conspiracy and said he never knew Oswald.
 Decades later, photos emerged establishing that Ferrie had been in the same Civil Air Patrol unit as Oswald in the 1950s, but critics have argued this does not prove that either Ferrie or Oswald was involved in an assassination plot.
