Procedure
A number of factors are taken into consideration when designating an event as a National Special Security Event. Department of Homeland Security press releases usually cite the following factors:
- Anticipated attendance by dignitaries. Events attended by officials of the United States government or foreign dignitaries may create an independent federal interest to ensure that the event transpires without incident and that sufficient resources are brought to bear in the event of an incident.
- Size of the event. A large number of attendees and participants generally increases security requirements. In addition, larger events are more likely to draw the attention of terrorists or other criminals, particularly those interested in employing weapons of mass destruction.
- Significance of the event. Some events have historical, political, cultural, or symbolic significance that may heighten concern about possible terrorist acts or other criminal activity.
- Duration of the event. State and local law enforcement and public safety agencies may possess the manpower and other resources to provide adequate security for a major event within their jurisdiction (e.g. World Series, NASCAR race, Super Bowl, televised awards show), but is unable to do so for events over several days or weeks and at the same time continue to meet routine obligations in the greater community.
- Availability of state and local resources. When state and local jurisdictions lack the expertise, experience, manpower or other assets needed to ensure comprehensive protection of these major events of national or international significance.
- Multiplicity of Jurisdictions. Extensive coordination of law enforcement and public safety agencies from multiple jurisdictions.
- Threat assessments. Anticipation of terrorism, or extensive illegal civil disobedience or other criminal activity.
When an NSSE is declared, the Secret Service becomes the lead agency for the security planning for the event; the FBI takes lead responsibility for counterterrorism, counterintelligence, criminal investigations; and FEMA takes lead responsibility for crisis management. Like the FBI and FEMA, the Secret Service brings in local law enforcement, public safety, and military experts to assist with developing the plan, and give them the special guidance and training to operate within the security plan.
Typical NSSE security measures include:
- Interagency coordination and interoperability
- Heavy police (days off and leaves may be canceled) and often National Guard presence
- Police dogs for bomb detection
- Surveillance
- WMD detection, mitigation, and decontamination
- Sharpshooters and other tactical capabilities
- Flight restrictions around the area
- United States Coast Guard patrols
- Increased railroad security
- Extensive road closures
