Who Was Lee Harvey Oswald?

The first time I saw this program was on PBS, I thought it was wonderful. Seeing what may have driven Lee Harvey Oswald to murder, seeing life through his eyes. By the end of this program i felt like they should make a movie of Oswald, not saying that he did or didn't killed the president. Letting you decide the outcome. By not growing up with is family, ether because they moved away or were at work, Oswald would go to the zoo. The outcome, Lee Oswald raised him self to what he became later in life. I also think that it was a nice touch that they used Gary Oldman as the voice of Oswald, seeing he played him in the movie "JFK". I'v tried everywhere to see if i can find it. I just hope that it will come on again so i can record it.
