Well, that surprises me, because that trial was a hot mess. JA should have never taken the stand. It made the entire trial a disaster.
CW would be well served if he did not take the stand either. Let the defense present their case, evidence, and let the prosecution prove without a reasonable doubt regarding the charges. Even if a juror decides that they cannot convict on killing the children, it is based on evidence and his own statement that he killed SW and Nico. Circumstances aside, he deliberately killed her, and hid the body. That alone can give him life in prison.
But, my own preference is that he is convicted on all counts.
