Since the initial publication of Law Enforcement Intelligence: A Guide for State, Local and Tribal Law Enforcement Agencies in November 2004, there have been a number of significant changes that have once again had an impact on law enforcement intelligence. While the field is continually evolving, many of the changes have been captured in the second edition of this publication. In fact, 85 percent of the content is new including new chapters on intelligence-led policing; civil rights and privacy in the law enforcement intelligence process; public-private partnerships; fusion centers; suspicious activity; and open source information. This publication takes a comprehensive look at these topics as well federal and national law enforcement intelligence resources, networks, systems, human resources, and anticipated changes to the classification system moving from Sensitive But Unclassified information to Controlled Unclassified Information.
