Investigative Interviewer's Guidebook in its 25th year of publication (revised). We provide the reader with comprehensive and in-depth information on the art and science of interview, interrogation, eyewitness evidence, and how to develop a working, competent understanding of law and technology. This triad creates a synergistic and unmatched ability to obtain information in our technically-coupled, compliance-heavy world...and from the best source there is - The human! The author has relied on his years of professional experience, academic achievement, teaching, and training experience to present accurate information in a user-friendly format and to help the reader understand how the interview and interrogation processes interrelate. The greater your investigative interviewing is, the greater the frequency and thoroughness of success in getting to the truth. Coverage includes: Interview and Interrogation: the interview, setting, question formation, background considerations, rapport building, interpretations of verbal and nonverbal deceptive behavior as well as rationalizations, denials, obtaining and enhancement of the admission as well as methods to optimize the interrogation of your subject. Eyewitness evidence: legal considerations, how the memory works, how to perform a proper interview, and other issues that impact this sensitive area. Law and Technology: Developing competitive skills in relevant aspects of law and technology.
