Intelligence information is discussed, identification specified, and emergency options outlined. Prior to the arrival of the protectee, checkpoints are established, and access to the secured area is limited. During the visit, Secret Service and local law enforcement personnel form a network of support for members of the detail surrounding the protectee. The Secret Service command post acts as the communication center for protective activities, monitors emergencies, and keeps all participants in contact with one another. After the visit, agents analyze every step of the protective operation, record unusual incidents, and suggest improvements for the future.
Protective research is an important ingredient in all security operations.
Technicians and engineers develop, test, and maintain technical devices and equipment needed to secure a safe environment for the Service's protectees. Agents and specialists assigned to protective research also evaluate information received from other law enforcement and intelligence agencies regarding individuals or groups who may pose a threat to protectees. This information is critical to the Service's protective planning. The Secret Service Uniformed Division, initially a force comprised of a few members of the military and the Metropolitan Police Department, began formalized protection of the White House and its grounds in 1860. This unit was under the direction of the White House Military Aide until 1922 when President Warren G. Harding prompted the establishment of a White House Police Force.
