Yes, R. Kelly is probably guilty as sin. That said, the girl and her parents said is wasn't her. Had I been on the jury, I likely would have voted the same way, and that is as it should be.

In our system, the defendant should be presumed innocent, and his or her guilt should be proven beyond a reasonable doubt. (I say should because I know this doesn't always happen in practice). This means that the guilty will sometimes go free, in order to ensure the innocent are protected. The system worked. So be it.
