What is fbi

Overview

The Federal Bureau of Investigation (FBI) is the domestic intelligence and security service of the United States, operating under the jurisdiction of the U.S. Department of Justice. As a federal agency, the FBI has authority to investigate crimes that cross state lines or violate federal law, distinguishing it from local and state law enforcement agencies.

History and Establishment

The FBI was founded in 1908 as a division within the Department of Justice. Over its more than century-long history, the agency has evolved from investigating interstate commerce violations to becoming a comprehensive federal law enforcement and counterintelligence organization.

Primary Responsibilities

The FBI handles investigations across multiple domains:

• Counterterrorism and counterintelligence operations
• Cybercrime and online fraud investigations
• Organized crime and racketeering cases
• Public corruption at federal level
• Civil rights violations and hate crimes
• Bank robberies and financial crimes

Structure and Operations

The FBI maintains 56 field offices in major U.S. cities, specialized divisions for different crime categories, and regional crime laboratories. The agency employs approximately 35,000 personnel including special agents, analysts, and support staff. Internationally, FBI legal attachés (Legats) stationed in U.S. embassies coordinate investigations with foreign law enforcement.

Technology and Databases

The FBI operates critical law enforcement databases including the National Crime Information Center (NCIC) and Fingerprint Identification System (FIS). These systems are accessible to authorized law enforcement agencies nationwide, facilitating information sharing and criminal investigations.
