"I'm not trying to justify anything. I'm just trying to tell my side of the story"

O.J. Simpson's quote suggests that he is trying to explain his point of view on a particular scenario. He is not attempting to excuse or defend his actions, however rather to supply an explanation for why he acted the way he did. This might be interpreted as an effort to provide context for his actions, or to supply a description for why he believes he is not guilty of the charges versus him. It might also be translated as an effort to supply a more total image of the events that took place, as Simpson might feel that his side of the story has actually not been adequately represented. Eventually, the quote recommends that Simpson is attempting to provide an explanation for his actions, instead of attempting to justify them.
