Was Kennedy Shot by only three bullets?

In an ABC video, Dale Meyers gives his take on the "single bullet theory". In this video he states that Lee Oswalt was the only killer of President John F. Kennedy. He generates a computer graphics analyzation of the Zapruder film. In this you can see the assassination from more than just one angle. He then provides strong evidence that their could be only one shooter. Lee Harvey Oswalt. They show a computer graphic of the shooting on how as soon as John F. Kennedy gets shot, Connaly made a reaction to the shot. They then were able to show that from the spot of where Kennedy was shot, they drew a line from Kennedy's shoulder to the window of the school book depository to the exact window where Lee Harvey Oswalt was shot.

After watching this film, I thought that Dale Meyers had a legitamite point on the shooting. I think he backed his hypothesis up with some strong details in his computer animation. I am currently undecided on the assassination. Meyers shows strong evidence, but I find it hard to believe that one single bullet could take that many "unexpected turns" and still end up in perfect condition. However, it is also hard to belive that their was a conspiracy, due to the majority of witnesses that claimed only three shots were heard. Plus, the guy who got "chipped by a bullet" I think that might have not been by Oswalt. Was he really shot by accident? Or was it intended? There are many diffrent questions surrounding the Kennedy assassination. There might be a day where we find out the truth, but for now the case is covered in a veil of mystery.
