Polygraph Examinations 

It is the purpose of this policy to provide investigative officers and others with general knowledge of, guidance, and procedures for the use of polygraph examinations.

The polygraph examination is a valuable investigative aid when used in conjunction with, but not as a substitute for, a thorough investigation. The polygraph may be employed, consistent with this policy, to verify, corroborate, or refute statements; obtain additional investigative leads; narrow or focus criminal investigations; screen candidates for positions with this or other criminal justice agencies; and assist in the conduct of internal police investigations, among other authorized purposes.
