Confessions are generally motivated by a desire to reduce fear and minimize consequences. Sometimes "hard techniques" designed to intimidate or threaten a person may result in an unreliable or fabricated confession. Providing a person with justification for his/her guilty wrongdoing is the key to getting a confession. The paradigm shift in gaining intelligence involves motivating the person to provide information by developing a relationship, bond or attachment with the interviewer. The use of "soft techniques" can often yield more information. In his book "Liar: The Art of Detecting Deception and Eliciting Responses," Mr. McManus offers readers tried and true methods of effective interrogation techniques. From the early history of deception through modern deception practices, Mr. McManus provides a solid foundation on which the reader can build his/her effective deception detection skills. A must read for those in law enforcement, intelligence and security communities.
