I noticed Maline towards the end of his speech turning over pages and pages that he didn't use. He even said I'm not using these because McGee has already covered it. Makes zero sense given that McGee already tried to weasel out of his responsibilities by saying earlier he turned over his notes to Maline when they were planning closing speeches and Maline didn't tell him about the court's order. So I think Maline had a chunk of stuff he knew he would get in trouble for and decided not to risk it after McGee's dressing down.
I think the silence at the end was an appalling gimmick. Merritt does not have tears inside him for the family he killed or the surviving family members, IMO. We've heard him in the Feb 17th audio, we've seen him on CNN, we've seen him over 5 months unflinching through it all. That is abuse in my world. That was their attempt to focus on him and his reaction, not the McStays, all because he didn't testify.
