Nancy Grace is also showing that slow motion video when she is angry and it is scary...Nancy seems to think it is when Baez moves from in front of the camera and she realizes the camera can see her she changes???
IMO it doesn't have anything to do with the camera. If it had to do with the camera she wouldn't be flailing her arm with her finger hook and gnashing her teeth like Hannibal Lectcher. She was caught in a unguarded moment and was freaking out to CM about JB. When JB turned around, she pulled a fast one. After she touches her neck, she then leans over toward CM, covers her mouth and continues to speak. Some of the video clips stop short of her talking to CM after the outburst.
