OJ was tried in LA. Juries can be VERY different in LA. Blake, Spector, von Bulow....AND, Ito fell in love with the camera, and lost control of the courtroom. Thus, the defense was allowed to make some crazy claims. Also, Ito allowed the defense to turn the trial into a racial issue.
Casting doubt still requires evidence. JG has too much evidence AGAINST any participation. This includes two passed FBI polygraphs and NO DNA. Moreover, KC is still insisting that it's Zanny. It's too late to jump on the JG train. Moreover, JG has shown no evidence of "obsession" he has not stalked KC. SHE initiated most of the calls to HIM. AND, JG and Ricardo have both cooperated with LE. KC has not. Nor has her family.
Ricardo has been cleared. How is JB going to build a case against a four-years-absent bio dad?
You need evidence to point to that Bushy Haired Stranger. You can't just point around the room and say, "Maybe it was somebody else." If that was the case, pretty much everybody would go free. There has to be some evidence, before there is doubt, honey!
