LAPD Polygraph Policy Documents Disclosed

AntiPolygraph.org has obtained and published two previously unavailable Los Angeles Police Department (LAPD) polygraph unit policy documents.

The LAPD Polygraph Unit Examiner Reference Guide dated November 2018 and marked “Law Enforcement Sensitive” includes rules for scoring polygraph charts as well as question sequences for the various polygraph techniques used by the LAPD polygraph unit, including the Law Enforcement Pre-Employment Test format used for screening applicants.

The LAPD Technical Investigation Unit Polygraph Unit Guidelines dated May 2019 detail the organization of the LAPD polygraph unit, the duties and responsibilities of its personnel, and its internal policies and procedures.

Polygraph Law Enforcement Accreditation

In 2011, AntiPolygraph.org reported that a consortium of federal, state, and local law enforcement agencies had created a “Polygraph Law Enforcement Accreditation” (PLEA) program and had in 2010 promulgated a 65-page “Polygraph Guide for Standards and Practices,” a copy of which we obtained and published (1.9 MB PDF).

The PLEA consortium continues to function and by 2018 included the Greenville, South Carolina Police Department, the Houston Police Department, the Los Angeles Police Department, the North Carolina Bureau of Investigations, the Pennsylvania State Police, the Virginia State Police, and a federal representative from the National Center for Credibility Assessment.

AntiPolygraph.org has obtained a newer, 78-page copy (1 MB PDF) of the PLEA Polygraph Guide for Standards and Practices dated 25 October 2018. Like the 2010 edition, it is marked “Law Enforcement Sensitive” on each page, with an additional caveat: “Do Not Copy.” Oh well.

The 2018 edition of the guide includes three new chapters covering, respectively, the Directed Lie Comparison Test (Ch. 11), the Directed Lie Screening Test (Ch. 12), and the Concealed Information Test (Ch. 13).

New Law Enforcement Polygraph Handbook

Polygraph Law Enforcement AccreditationAs the American Polygraph Association holds its annual seminar in Austin, Texas this week, one of the topics on the agenda is a program run by a consortium of federal, state, and local law enforcement agencies called “Polygraph Law Enforcement Accreditation” (PLEA). Participating agencies include the Customs and Border Patrol (CBP), the Defense Criminal Investigative Service (DCIS), the Los Angeles Police Department (LAPD), and the Houston Police Department.

The PLEA consortium, whose motto is “Semper Veritas” (truth always), has promulgated a 65-page “Polygraph Guide for Standards and Practices” that sets forth procedures and protocols to be used by participating agencies. AntiPolygraph.org has received a copy of this guide, each page of which is marked “Law Enforcement Sensitive Information,” and has made it available for download here (1.9 MB PDF). Chapter 10 will be of special interest to applicants for employment with agencies participating in the PLEA consortium.
