“The ‘indicators’ they use are small face movements, head tips”
I used to watch that Tara person on O’Reilly, and did learn some things.
Hubby and I watch ID and oxygen sometimes — true crime stuff. They’ll show actual interrogations with suspects. A couple times I’ve said, “He’s lying” by watching the guy’s head. A basic one is saying the word, “Yes”, while unconsciously shaking the head. And the reverse, saying, “No”, but nodding the head. Amazing how often than happens. Whatever the head says usually is truer than the words.
I watch the same shows. Every now and then they show the actual live interview by the police. They seem to always do protective type things when they are guilty. Arms across the chest, leaning back in the chair.
My brother was murdered by his wife about 15 years ago. His story was made into an episode of Snapped. They did a fairly good job of recounting the facts.
