September 11th... Pearl Harbor... the assassination of JFK. Days that forever changed America. But the Kennedy assassination is different: 50 years after it happened, most Americans think we don't know who did it. Now HISTORYTM has conducted the largest nationwide survey ever attempted on the topic to learn exactly what the country believes. Who do Americans suspect was really responsible for JFK's death? It's an entirely new way to look at the assassination through the eyes of those to whom it matters most: the American people. Experts Vincent Bugliosi, Max Holland, Gerald Posner, Robert Groden, Jefferson Morley and others break down why each leading theory has captured the American imagination, where the evidence supports it, and where it comes up short. The entire range of conspiracy theories is examined, from the mainstream to the fringe, and the big questions are finally answered: who does America think really killed JFK...and why?
