Unit Description

The Polygraph Team is staffed by detectives who have undergone rigorous and lengthy training to become certified polygraph examiners. The use of the polygraph, or what is commonly referred to as a “lie-detector”, is a valuable investigative tool utilized in all sorts of criminal investigations. The polygraph operates by measuring changes in various physiological responses to a series of questions and answers. The examiner must interpret those measurable changes as indications of deception.
