The federal government of the United States empowers a wide range of law enforcement agencies to maintain law and public order related to matters affecting the country as a whole.

Overview[edit]

Federal law enforcement authorities have authority, given to them under various parts of the United States Code (U.S.C.). Federal law enforcement officers enforce various laws, generally at only the federal level. There are exceptions, with some agencies and officials enforcing state and tribal codes. Most are limited by the U.S. Code to investigating matters that are explicitly within the power of the federal government. Some federal investigative powers have become broader in practice, since the passage of the USA PATRIOT Act in October 2001.

The Department of Justice was formerly the largest, and remains, as of 2014, most prominent collection of law enforcement agencies, and handled most law enforcement duties at the federal level.[1] It includes the United States Marshals Service (USMS), the Federal Bureau of Investigation (FBI), the Drug Enforcement Administration (DEA), and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), Federal Bureau of Prisons (BOP), and others. In 2002, the Department of Homeland Security (DHS) was created by an act of Congress.

There is also U.S. Customs and Border Protection (CBP) which includes the Office of Air and Marine, the Office of Border Patrol, and the Office of Field Operations. CBP's components have the primary responsibility of enforcing customs and immigration laws at and between the ports of entry of the United States; the Federal Protective Service (FPS) is responsible for federal law enforcement in federal buildings and properties. Including elements of the U.S. Coast Guard and the U.S. Transportation Security Administration, DHS now has more sworn armed federal law enforcement agents and officers than any other department of the United States government.

While the majority of federal law enforcement employees work for the departments of Justice and Homeland Security, there are dozens of other federal law enforcement agencies under the other executive departments, as well as under the legislative and judicial branches of the federal government.

History[edit]

Federal law enforcement in the United States is well over two hundred years old. For example, the Postal Inspection Service can trace its origins back to 1772.[2]
