The main policing body of any government (i.e., police officers) is charged with the regulation and control of the affairs of the community, now chiefly the department established to maintain order, enforce the law, and prevent and detect crime.¹ Police officers make up the body of persons, who are trained in methods of law enforcement and crime prevention and detection and authorized to maintain the peace, safety, and order of the community.¹
The Federal law enforcement possesses authority, which is given to them under a variety of parts of the United States Code (USC).² The Department of Justice, formerly the largest enforcement agency, is the most prominent collection of agencies and handles most law enforcement duties at the federal level.²
This 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).² The Department of Homeland Security (DHS) was created in 2002 by an act of Congress. The majority of federal law enforcement employees work for the departments of Justice and Homeland Security.²
