The judge overruled the jury on the ground that the prosecution failed to establish a violation of the law. Which is what judges are ultimately there to do. Juries aren't intended to understand the law, only to understand the facts and decide based on their perceived veracity.

Again, this was a shit ruling by a shit judge and upheld by a shit appellate court. But the problem was the circumstance not the system. Judges can and do periodically overturn jury verdicts.

At some level, there's a distinction between the system and the people participating in it.
