FBI Domestic Investigations and Operations Guide (DIOG) 2008 Version Training Material and Related Documents

This release contains training material and other documents pertaining to Section 4 of the FBI’s Domestic Investigations and Operations Guide (DIOG). Section 4 of the DIOG outlines the FBI’s oversight, self-regulation, and strict adherence to the Constitution of the United States in dealing with “Privacy and Civil Liberties, and Least Intrusive Methods,” as the section is titled. The section states that the FBI is “responsible for protecting the American public, not only from crime and terrorism, but also from incursions into their constitutional rights.” (Page 32). We released this material on January 5, 2011, in answer to multiple FOIA requests for additional information on Section 4 and to explain more fully the established rules under which FBI employees carry out their mission with full respect for the constitutional and statutory rights of U.S. citizens. The section largely consists of presentations from two FBI components, the Corporate Policy Office and the Directorate of Intelligence. Documents in this release were created to provide instruction regarding the concepts and principles underpinning Section 4 of the DIOG. Redactions were made to protect personal privacy, internal personnel rules and practices, and law enforcement techniques and procedures. This release was partially updated on February 3 to make images more legible.
