What is one of the main functions of the Federal Bureau of Investigation (FBI), which is part of the DOJ?

The Federal Bureau of Investigation (FBI) primarily serves as the principal investigative agency and domestic intelligence service of the United States. One of its main functions is conducting criminal investigations. This encompasses a wide array of activities, including tackling federal crimes such as terrorism, cybercrime, organized crime, public corruption, civil rights violations, and violent crimes. The FBI plays a critical role in upholding the law and ensuring national security by collecting and analyzing intelligence, facilitating joint task forces, and collaborating with other law enforcement agencies at various levels.

The functions related to education policies, managing government, and overseeing public transportation do not fall under the scope of the FBI’s responsibilities, as these areas are typically managed by other government departments or agencies. For instance, education policies are usually the purview of the Department of Education, while public transportation and state and local governance typically involve local authorities and the Department of Transportation. Thus, the identification of the FBI's role in criminal investigations underscores its primary mission within the broader framework of national security and law enforcement in the United States.
