Course Description:

This course is constructed specifically for law enforcement officers. The focus of training is to familiarize the new and seasoned investigator with the various disciplines of "detecting deception". This is accomplished through learning to read non-verbal body language, neurolinguistics, and by being introduced to the newest form of conducting detailed analysis of verbal and written statements.  Investigators are encouraged to conduct interviews and interrogations in such a structured fashion as to practice court-preferred methods of obtaining confessions.


This course is offered to all officers regardless of prior experience or training level. Since law enforcement officers seldom remain in a stationary position of administration, patrol or investigation, this training is appropriate for all. From the "rookie officer" recently graduated from the academy to the seasoned polygraph and criminal investigator, every attendee will benefit from this valuable training. The only prerequisite is that the officer must deal with other human beings regardless of their capacity and have the ultimate need to be able to determine truth and deception.
