Federal Law Enforcement in the United States

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.

These agencies are a mixture of direct law enforcement agencies, for example the Federal Bureau of Investigation (FBI), regulatory authorities with law enforcement powers, for example the United States Environmental Protection Agency, and other agencies with police units, for example the United States Department of Veterans Affairs Police.

History

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.
