The Deception Detection guidebook is not intended to provide a thorough explanation of the various concepts involved in Statement Analysis, Body Language, or Deception Detection. This handbook is intended to be used as a reference for supervisors, Law Enforcement Officers, or other deception detectors to quickly refresh or review the various concepts. This guide is not written in a chapter format, but seeks to provide a quick overview of the various concepts/topics and to provide the reader with the core of the information. It is meant to be a small handy guidebook that can fit in one's pocket; giving access to the desired information without the need to sift through long case studies or filibustered material in order to review/recall the basic principles.
