American Police Hierarchy

The American Police system is divided into various types of agencies such as federal law enforcement agencies, state police departments, sheriff’s departments, municipal police and special police agencies like transit police and school police. The various major law enforcement agencies are Federal Bureau of Investigation (FBI), Bureau of Alcohol, Tobacco and Firearms (ATF), Drug Enforcement Administration (DEA), The U.S Marshals Service, The Secret Service, The Immigration and Naturalization Service (INS).

We will discuss the American Police Hierarchy in details specifying the various ranks and the specific job roles undertaken by each and every rank in the decreasing order of ranks.
