Integrating Intelligence explores how the present, ad hoc U.S. federal, state, and local intelligence enterprise developed, and analyses its prospects for continued evolution. Examining the types of threats that have warranted information sharing in past, Tromblay breaks down the structures of information sharing and current areas where information-sharing enterprises need to be strengthened at all levels of government to effectively disrupt threats to national security. This book provides a baseline understanding of how the federal, state, and local domestically-oriented intelligence enterprise has reached its modern organization, and creates a common point of reference for future intelligence agents to assess the enterprise's effectiveness and shortcomings. Intelligence, criminal justice, and public policy programs grapple with aspects of ensuring that the right information is shared and acted on in furtherance of national security. Practitioners - especially those responsible for developing the architecture for information sharing as well as those seeking a better understanding of the architecture they are using daily - will benefit from this invaluable source that explains how and why the current system has developed and what course corrections are necessary to ensure that information can be exploited by federal, state, and local authorities to achieve a unified approach to national security.
