Replying to Kennedy Assassination

Newschoolers, I'm writing a paper on the Kennedy Assassination, saying specifically that Oswald was, in fact, the only assassin. If any of you remember seeing that cool TV show with all the computer effects that replayed the whole event, it was ABC News Presents The Kennedy Assassination: Beyond Conspiracy with Peter Jennings. If anyone has this, or knows where I could watch it digitally, other than Amazon because I don't have the time or money, it would be much appreciated..
