FBI Interagency Liaison Manual Requirements

The FBI Manual of Instructions set formal requirements for interagency liaison, including that each Special Agent in Charge (SAC) designate specific agents responsible for developing and maintaining relationships with other federal agencies. These liaisons were required to consider shared agency interests, agency headquarters locations, and agency representative responsiveness, with goals of fostering close friendly relationships, mutual understanding of FBI and agency jurisdictions, and willingness to coordinate activities and discuss shared problems. Field offices were also required to identify local federal agencies with which liaison should be conducted.

Lawson of the White House detail.
