The general argument made by director John Singleton in his work 30 for 30: Marion Jones: Press Pause is that Marion Jones deserves what she had to go through after being caught for using performance enhancing drugs (PED's). He explains to you the whole process Jones went through that eventually landed her in Prison. He does this with having Jones giving you first hand stories and also first hand stories from her attorney. It is not presenting any arguments other than her being guilty and owning up to it after the fact that she lied about it several times to Federal investigators and  public press conferences. Marion Jones received six months jail time on two accounts of lying to federal investigators. 

In my view Singleton made his documentary correctly. He used several good tactics to justify what he was trying to get across. He also had a great use of interviews and was fair to both sides of the story. He had good answers from people on Jones point of view and good interviews with people who  believed that Jones was guilty and deserved what she got. There fore i concluded that this was a very well made documentary.
