The 2019 edition includes materials for basic training, advanced training, and for field use. The Legal Training Reference Book is a companion to the Handbook. The Additional Resources section in it contains numerous pieces of legal information helpful in your day-to-day activities as a law enforcement officer. It is our hope in the Office of Chief Counsel that the Legal Training Handbook and Reference Book can serve law enforcement students and law enforcement officers alike. While this text provides an exceptional review of important legal concepts, you should not limit yourself to this publication.
