Understanding Polygraph Tests and Responses

The video tutorial introduces new content focusing on investigative interviews and polygraph tests. It details five persons of interest in a mysterious death case and explains how polygraph tests are used to detect deception through physiological responses. The limitations of polygraph tests in court are discussed, along with the interaction between the respiratory and cardiovascular systems.
