The article "Twenty Mysterious Minutes in Dallas" from the Christmas 2011 edition of "Dealey Plaza Echo" presents an argument by Alaric Rosman, claiming that the assassination of John F. Kennedy was a plot orchestrated by the CIA and Lyndon B. Johnson. Rosman delves into the details of the assassination, particularly the transfer of Kennedy's body to Washington for autopsy, which he considers critical evidence of the conspiracy. He argues that Johnson played a key role in manipulating the investigation to portray Oswald as the sole assassin, despite evidence suggesting a conspiracy. The article also addresses the confusion surrounding the rifle used in the assassination, questioning the official description of a Mauser and suggesting that a false clip was planted at the crime scene to frame Oswald. An excerpt from Barry W. Ernest's book "The Girl in the Staircase" is included, detailing his efforts to locate and interview Victoria Adams, a witness who did not see Oswald on the stairs of the Texas School Book Depository. The article concludes with a collection of interesting research documents, including a telegram from Earl Cabell to Allen Dulles, dated October 27, 1963.
