Devin, what could of government DO you want? Do you want one where whenever the police arrest someone they go before the judge for sentencing, with the assumption that they are guilty, and then we stick 'em in prison until they can prove that it wasn't them? Is that what you want? While I know you don't agree that 100 guilty people should go free so that an innocent person doesn't wind up in prison, that doesn't change the fact that every time someone is wrongly convicted, that means the real perpetrator of the crime is out there and able to commit more crimes. If, for example, there is a string of murders, and the police arrest John Q, and he cannot prove that he is innocent, even though there is doubt that he is guilty, your system would have him thrown in prison until he can prove that he didn't do it. While he is attempting to prove beyond reasonable doubt that he is innocent (instead of the prosecutor proving beyond reasonable doubt that he is guilty), the real murderer is out there and free to commit more murders. He may lay low for a while, or move to another part of the country, but he is out there and free. Is that justice?
You also have yet to prove that Casey is guilty. All you've said, when the question's been brought up, is that the jury is stupid and obviously wrong and Casey should be in prison. That is no more a good argument than me saying, if she were found guilty, that the jury is stupid and obviously wrong and Casey shouldn't be in prison. You've yet to prove anything. I should also think that the jury, who has spent every minute of the trial in the courtroom and spent many hours deliberating together (not to mention the time they must have spent in their rooms thinking about the day's events) over the trial, should be more able to get the right answer than you. Keep in mind that every juror voted that she was not guilty. Not just a majority, but every one. Otherwise the jury would have been hung.
Oh, and I didn't realize that if 40 people work together to cover up a murder, they aren't accomplices. You should let the mob know, I'm sure they'd love to use that the next time there's a big mob trial.
