The notion that police are primarily concerned with enforcing criminal law was popularized in the 1930s with the rise of the Federal Bureau of Investigation as the pre-eminent "law enforcement agency" in the United States; this however has only ever constituted a small portion of policing activity.[6] Policing has included an array of activities in different contexts, but the predominant ones are concerned with order maintenance and the provision of services.[7]
