He should of got off

I was routing for Scott Peterson due to the fact that there was no solid evidence that he committed the crime..But did his wife come from the bottom of the lake just in time for his conviction to tell on his actions...who knows, but what no one talked about was this chick disappeared about 2 years ago...shouldn't the body be bones by now?? did they find the bones of the baby..I'm confused, maybe i didn't follow the case to well but if some jury members had to get replaced because they didn't agree with the case isn't that a mistrial? They went ahead and found new jurors that was following the case and that should be a conflict of interest...I'm no lawyer but i like to ask a lot of questions especially if my freedom is in jepordy...
