Although sheriffs are not usually counted as police chiefs, their agencies usually have the powers and role of a police department. Some sheriffs' agencies are limited to non-policing matters such as courtroom security. The usual difference between a sheriff and a police chief is that sheriffs are elected (except in New York City, Rhode Island and Hawaii) and responsible for a county whereas a police chief manages law enforcement in a city or town and is appointed by its local government. The fraternal organization International Association of Chiefs of Police (IACP) is an organization that many chiefs of police are associated with.
