The Warren Commission conducted a 10-month investigation following the assassination. Although it was determined that Oswald acted alone, the Kennedy assassination is still the subject of widespread conspiracy theories. Surveys between 1966 and 2004 found that up to 80 percent of Americans thought that there was a plot to cover up the truth about JFK's murder.
