This course will explore the various ways of determining when a witness, victim or suspect is not telling the truth, more importantly, not telling the whole truth. The first part will cover the various techniques; statement analysis, kinesics (body language), behavioral analysis, and neuro- linguistics, to not only determine if an individual is being deceptive, but how to overcome the deception and obtain admissions and confessions. The second part will explore the various personality disorders most often seen in individuals who, more often than not, are involved in criminal behaviors (anti-social, narcissistic, borderline, paranoid, obsessive-compulsive) with a special emphasis on the criminal psychopath. These individuals pose a special challenge during an interview as their “disorders” make it easier to lie and often mask their stress of telling a lie.
