Polygraph Unit

polygraph-testThe Polygraph Unit has two certified examiners who conduct polygraph tests for criminal investigations and pre-employment screening.

When conducting a polygraph test, an instrument is used to measure the person’s body physiology. It then records the responses to the polygraph charts and the polygraph examiner analyzes the charts to determine if the person involved was being truthful or not.

In addition to testing, polygraph examiners also assist with other parts of investigations, including reviewing files, conducting interviews and analyzing statements.

Interesting fact: The polygraph test is often referred to as a “lie detector test” but a more appropriate name would be “Truth Verification Test” because most people tested (approx. 80%) are found to be telling the truth.
