Interpol

Interpol is the International Criminal Police Organization, an international body that enables police forces in 196 member countries to share information and coordinate efforts to combat transnational crime. Unlike common misconceptions in true crime narratives, Interpol is not a supranational police force with independent arrest authority—it cannot dispatch agents to apprehend suspects or conduct investigations on its own. Instead, it functions as a secure communications network and intelligence-sharing platform, maintaining databases on wanted persons, stolen property, fingerprints, DNA profiles, and travel documents that member countries' law enforcement agencies can access and contribute to.

In the United States federal system, the designated liaison to Interpol is the United States National Central Bureau (USNCB), also known as Interpol Washington, which operates under the authority of the U.S. Department of Justice. This bureau serves as the single point of contact between U.S. law enforcement agencies—federal, state, local, and tribal—and their counterparts in other Interpol member countries. The USNCB coordinates requests for international investigative assistance, processes and disseminates information on international fugitives, and facilitates cooperation on cases involving transnational criminal activity such as terrorism, human trafficking, cybercrime, and organized crime.

Interpol's most publicly recognized tool is the system of color-coded international notices, particularly the Red Notice—a request to law enforcement worldwide to locate and provisionally arrest a person pending extradition. However, a Red Notice is not an international arrest warrant; member countries retain full sovereignty over whether to act on such notices under their own legal frameworks. The organization maintains its General Secretariat headquarters in Lyon, France, and operates regional bureaus worldwide. In true crime contexts, Interpol typically appears when fugitives flee across international borders, when investigations require evidence or witness cooperation from multiple countries, or when law enforcement seeks to track suspects moving through international transportation networks.

The legal framework governing U.S. participation in Interpol includes 22 U.S.C. § 263a, which authorizes the U.S. representative to the organization, and 28 C.F.R. § 0.34 and Subpart F-2, which establish the Attorney General's authority to designate the USNCB and describe its coordinating functions. These regulations clarify that the USNCB integrates information for investigations of an international nature while respecting the jurisdictional boundaries and legal procedures of both U.S. law and the laws of cooperating nations.
