The following are some useful resources published by the US government and national organisations.
 | United Stated Secret ServiceThe U.S. Secret Service has grown from a small bureau staffed by a few operatives in 1865, to a law enforcement organization of nearly 7,000 employees worldwide. Today, the U.S. Secret Service fights crime on a global scale through its field offices located in the United States, Canada, Mexico, South America, Europe, Africa and Asia. The agency works closely with local, state and federal law enforcement organizations. These entities are valued partners of the Secret Service, and they are integral to the agency’s investigative and protective endeavours. |
 | The United States Department of JusticeThe Office of the Attorney General was created by the Judiciary Act of 1789 (ch. 20, sec. 35, 1 Stat. 73, 92-93), as a one-person part-time position. The Act specified that the Attorney General was to be “learned in the law,” with the duty “to prosecute and conduct all suits in the Supreme Court in which the United States shall be concerned, and to give his advice and opinion upon questions of law when required by the President of the United States, or when requested by the heads of any of the departments, touching any matters that may concern their departments.” |
 | The National Center for Missing & Exploited Children®The National Center for Missing & Exploited Children® opened in 1984 to serve as the nation’s clearinghouse on issues related to missing and sexually exploited children. Today NCMEC is authorised by Congress to perform 22 programs and services to assist law enforcement, families and the professionals who serve them. |
 | The Department of Homeland SecurityThe Department of Homeland Security has a vital mission: to secure the nation from the many threats we face. This requires the dedication of more than 240,000 employees in jobs that range from aviation and border security to emergency response, from cybersecurity analyst to chemical facility inspector. Our duties are wide-ranging, and our goal is clear – keeping America safe. |
 | The Central Intelligence AgencyThe Central Intelligence Agency was created in 1947 with the signing of the National Security Act by President Harry S. Truman. The act also created a Director of Central Intelligence (DCI) to serve as head of the United States intelligence community; act as the principal adviser to the President for intelligence matters related to the national security; and serve as head of the Central Intelligence Agency. The Intelligence Reform and Terrorism Prevention Act of 2004amended the National Security Act to provide for a Director of National Intelligence who would assume some of the roles formerly fulfilled by the DCI, with a separate Director of the Central Intelligence Agency. |
