You and I may know in our hearts that OJ was guilty. However, do we know for an absolute fact that he really was guilty?
If I am not wrong, OJ actually wrote a biography later, in which he detailed on how he murdered his ex-wife (Nicole Brown Simpson) and Ronald Lyle Goldman. How can you argue that he is innocent, after all this evidence. And in the United States, many people are sentenced to death or life without parole, with even less evidence.
