Question: Who was born more recently, James Files, or Lee Harvey Oswald?

Context paragraphs:
Jim Leavelle: James Robert Leavelle (born August 23, 1920) is a Pearl Harbor veteran and the former Dallas, Texas, homicide detective who was escorting Lee Harvey Oswald through the basement of Dallas Police headquarters when Oswald was shot by Jack Ruby.  Widely distributed photographs of Oswald shortly before the shooting, depict Leavelle standing to Oswald's right and wearing a light-colored suit with matching hat.

James P. Hosty: James Patrick Hosty Jr. (August 28, 1924 – June 10, 2011) was an American FBI agent assigned to investigate Lee Harvey Oswald upon Oswald's June 1962 return to the United States after his defection to the Soviet Union.  After Hosty made contact with Marina Oswald (a Soviet citizen) in order to interview her about her recent entry into the United States, Oswald wrote him a letter to protest the "harassment" of his wife Marina, and had Hosty's name and phone number in his address book.  After the Kennedy assassination, Hosty did not disclose Oswald's letter about Marina to the Warren Commission and destroyed it on his superior's order.  Because of this, Hosty attracted speculation as a possible conspirator in several conspiracy theories.  Hosty was transferred to the FBI's Kansas City office until his mandatory retirement in 1979.  Hosty later wrote a memoir about the Kennedy assassination, titled "Assignment: Oswald".

John Pleshette: John Pleshette (born July 27, 1942) is an American actor and screenwriter, best known for his role as Richard Avery on the television drama "Knots Landing", and for portraying Lee Harvey Oswald in the TV movie "The Trial of Lee Harvey Oswald".  Pleshette also wrote several scripts for "Knots Landing" in the 1980s.

The Trial of Lee Harvey Oswald (1964 film): 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.

James Files: James Earl Files (born January 24, 1942), also known as James Sutton, is a former American prisoner.  In 1994, while serving a 50 year sentence for the 1991 attempted murders of two police officers, Files gave interviews stating that he was the "grassy knoll shooter" in the 1963 assassination of United States President John F. Kennedy and that Lee Harvey Oswald never fired a single shot.  Files has subsequently been interviewed by others and discussed in various books pertaining to the assassination and related theories.  In 1994, the Federal Bureau of Investigation was quoted as having investigated Files' allegation and found it "not to be credible".

Lee Harvey Oswald: Lee Harvey Oswald (October 18, 1939 – November 24, 1963) was an American former U.S. Marine who assassinated United States President John F. Kennedy on November 22, 1963.  According to four federal government investigations and one municipal investigation, Oswald shot and killed Kennedy as the President traveled by motorcade through Dealey Plaza in the city of Dallas, Texas.

John F. Kennedy assassination rifle: 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.

Marina Oswald Porter: 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.

The Trial of Lee Harvey Oswald (1977 film): 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.

Hugh Aynesworth: 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".
