Pour détecter si quelqu'un ment ou non :
-# Look for deceptive behaviors and responses within the first five seconds of asking a question.
-# Someone telling the truth will say immediately and plainly that they did not commit the crime.
-# Liars often respond to questions with truthful statements that cast them in a favorable light.
-# Liars often repeat a question to stall for time, go into attack mode against the questioner or butter up the questioner with compliments.
-# Nonverbal cues to lying include hiding the mouth or eyes, throat clearing or swallowing, grooming gestures like adjusting shirt cuffs, shifting weight around and sweating.
