Why do agencies use polygraph?
Honesty and integrity are fading qualities in today s society; few role models exhibit these qualities. As a law enforcement officer you are granted the authority to deny a person their civil rights. No one else has such authority and no other right is so protected by our citizens. Agencies are held accountable for what type of individuals they allow to hold those positions. Many states require that departments conduct a background investigation and/or psychological exam. However, some information may not come up in a background investigation, especially if an individual has concealed information, thus the need for lie detection methods.
