Law Enforcement Intelligence Critical Functions was developed to serve three different, yet related functions:

• Assist the law enforcement operational units to identify and understand the guidance they must provide to the intelligence unit supporting their operation or investigation.
• Assist the law enforcement intelligence unit to understand the types and forms of intelligence operational and investigative units require to perform their various law enforcement functions
• Assist the law enforcement mission managers in understand the functions of both enforcement and intelligence units, and how those units interact to provide a successfully law enforcement outcome.

Initially most of the contents of the book were developed as instructional handouts used to accompany various training classes I have conducted while working as a police officer or on active duty. The notes, along with other research, have been assembled for this publication.
