Emergency Communications

Programs that provide services, often through one or more intermediaries, which enable two or more parties to communicate in emergency situations where normal means of communication are unavailable. Included are individuals (such as amateur radio or CB operators) and organizations (such as Amateur Radio Emergency Service) that provide alternative communications channels following a major disaster or large-scale emergency that disrupts the normal functioning of a community.

Emergency Law Enforcement Support

Federal and state organizations that provide support to local law enforcement agencies if their resources are overwhelmed. The state National Guard may be mobilized by the Governor at the request of local authorities. Federal troops may be used when state and local law enforcement resources are exhausted, and are mobilized when the Governor submits a request in writing to the Attorney General of the United States. Services may include police units that are trained in handling large crowds and riot situations; SWAT teams that specialize in high-risk situations requiring special tactical skills; law enforcement dive teams that are used to recover evidence, drowning victims or lost vessels; patrol dogs that help to apprehend offenders, detect intruders, find lost children or handle other police work; and canine units that are trained to detect cadavers, explosives or narcotics.
