A. Plan of the Investigation (110 words)

The purpose of this investigation is to examine the assassination of the former U.S. president John F. Kennedy, which occurred in Dallas on the 22nd of November 1963. More precisely, this investigation will focus on the question whether the assassination was an act of Lee Harvey Oswald alone or if there were more shooters involved in the events at the Dealey Plaza. Research was initiated through online research of declassified U.S. document archives to provide primary sources and websites of different historians to provide secondary sources. These sources were then evaluated and annotated in the bibliography, in which both the information presented and the sources of the information were analyzed.            

B. Summary of Evidence (803 words)

Source 1: Report of the President's Commission on the Assassination of President Kennedy published by The National Archives

Based on the evidence analysed, the Warren Commission concluded that three shots were fired from a window in the sixth-floor of the Texas School Book Depository Building at the events of the assassination. Two bullets presumably caused all the damage done to Governor Connaly and John F. Kennedy (single bullet theory) and the other bullet probably missed the presidential limousine completely. It was, furthermore, concluded that Lee Harvey Oswald fired all three of the shots in a time period ranging from approximately 4.8 to 7 seconds.

Source 2: Report of the Select Committee on Assassinations of the U.S. House of Representatives by the National Archives

The Select Committee on Assassinations of the U.S. House of Representatives (HSCA) considered all the evidence available to the number of shots fired, including the transmissions received over the police radio network from officers in the field that were recorded at Dallas police headquarters and witness testimonies on the shots, and came to the conclusion that the scientific acoustical evidence established a high probability that more than one gunman fired at president Kennedy.  A further conclusion by the HSCA is that he was probably assassinated as a result of a conspiracy, although the committee was unable to identify the other gunmen or the extent of the conspiracy, it noted that it believes that the governments of the Soviet Union, Cuba, the FBI, the CIA or the Secret Service were part of such a conspiracy.
