The judge didnt back up what you said. The Judge gave his opinion, which in terms of a jury is equal to the other 12 jurors opinion. Furthermore, the Judge explicitly stated that the evidence " not necessarily of premeditated murder, but certainly all lesser charges."
Well that is great, he is entitled to his opinion, but the only opinions that count are the Jury. And that is how the American legal system works, you are tried by a jury of your peers. I cant believe people still care about this, in the words of Snoop/ Slick Rick "This type of s*** happens every day".
Jenks earlier remarked about how you win some you should lose and you lose some you should win. That is the nature of the court system. She was found innocent, we move on.
