Which agency primarily focuses on investigating federal crimes?

• A. U.S. Supreme Court
• B. Federal Bureau of Investigation
• C. State Police
• D. City Police

Answer: (B)

The Federal Bureau of Investigation (FBI) is the agency that primarily focuses on investigating federal crimes. Established in 1908, the FBI is a federal law enforcement agency under the United States Department of Justice. Its primary responsibilities include protecting and defending the United States against terrorist and foreign intelligence threats, enforcing criminal laws, and providing leadership and criminal justice services to federal, state, municipal, and international agencies.

The FBI investigates a wide range of federal offenses, including but not limited to terrorism, organized crime, cybercrime, public corruption, civil rights violations, and white-collar crimes. Its jurisdiction extends across all states and territories, meaning it is equipped to handle crimes that cross state lines or that involve national interests.

In contrast, the U.S. Supreme Court serves as the highest court in the federal judiciary but does not investigate crimes; its role is to interpret laws and adjudicate legal disputes. State police generally focus on enforcing state laws and investigating crimes within their respective states, while city police handle law enforcement within municipal boundaries, primarily focusing on local crimes. Both state and city police have limited jurisdiction compared to the FBI, whose authority spans nationwide and encompasses federal statutes.
