Im just doing a ignment on OJ Simpson?

im only 16 yrs old and ive never heard of his crime before but as i read about him i feel disgusted and i dont undertsand how someone could get away with it i still dont even know is he is guilty or innocent but when i look at the way he acts and his look i keep thinking he is guilty. not because im racist im truley not most of my friends are darker skinned. How could the justice system fail so badly
