It can also be that the Jury hasn't seen or heard the evidence that we think is relevant or shows guilt or innocence. The defence or prosecution may not be aware of it, the evidence was not allowed by the judge because of reason X, many different reasons.
Indeed. I was on a jury a few years ago, and the defense and prosecution had made a deal to exclude particulars of the defendant's past. Basically he'd done it before, but in exchange for the prosecution not bringing that up the defense wouldn't bring up the defendant's mental illness history. So we the jury were unaware of all that, but the newspapers reported it. If we'd happened to let him off we'd have seemed insane to the public. (As it happened we potted him because in addition to overwhelming evidence he confessed on the stand.)
