Dateline NBC (10 p.m., NBC) - “Dateline” will air rarely-seen video of killer Robert Durst’s friends testifying as to why Durst may have killed his best friend, Susan Berman. It’s pre-recorded testimony that may be used at Durst’s trial next year. We hear from friends Nick Chavin and Emily Altman. “Dateline” also has a recording, more than 30 years old, of Berman discussing the disappearance of Durst’s first wife, Kathie. If you don’t know the story of Robert Durst and his many bad deeds, do whatever it takes to watch the HBO documentary series “The Jinx” as soon as possible. It’s unbelievable.
