He paints his data with descriptive examples of scientific studies and literature, everyday life and politics. Voice tone, body language and facial expressions while pointing to that person lying, how can the judges, the police, and even the Secret Service agents be able to bleed on the lie. Ekman is taking the seriousness that he deserves to use the clever signs of deception.
