In the early 19th century, various cities in Scotland and Ireland had established their own police forces. Sir Robert Peel is typically credited with the lead role in bringing a police force to London via the passage of the Metropolitan Police Act of 1829. Indeed, the early London police were often called "peelers."
Either Peel or the early commissions of the London Police Force wrote down nine principles of policing, which have been fairly well-known since then to police everywhere. Here are "9 Policing Principles" are as listed at the website of the Law Enforcement Action Partnership.
- To prevent crime and disorder, as an alternative to their repression by military force and severity of legal punishment.
- To recognize always that the power of the police to fulfill their functions and duties is dependent on public approval of their existence, actions and behavior, and on their ability to secure and maintain public respect.
- To recognize always that to secure and maintain the respect and approval of the public means also the securing of the willing cooperation of the public in the task of securing observance of laws.
- To recognize always that the extent to which the cooperation of the public can be secured diminishes proportionately the necessity of the use of physical force and compulsion for achieving police objectives.
- To seek and preserve public favor, not by pandering to public opinion, but by constantly demonstrating absolute impartial service to law, in complete independence of policy, and without regard to the justice or injustice of the substance of individual laws, by ready offering of individual service and friendship to all members of the public without regard to their wealth or social standing, by ready exercise of courtesy and friendly good humor, and by ready offering of individual sacrifice in protecting and preserving life.
- To use physical force only when the exercise of persuasion, advice and warning is found to be insufficient to obtain public cooperation to an extent necessary to secure observance of law or to restore order, and to use only the minimum degree of physical force which is necessary on any particular occasion for achieving a police objective.
- To maintain at all times a relationship with the public that gives reality to the historic tradition that the police are the public and that the public are the police, the police being only members of the public who are paid to give full-time attention to duties which are incumbent on every citizen in the interests of community welfare and existence.
- To recognize always the need for strict adherence to police-executive functions, and to refrain from even seeming to usurp the powers of the judiciary of avenging individuals or the State, and of authoritatively judging guilt and punishing the guilty.
- To recognize always that the test of police efficiency is the absence of crime and disorder, and not the visible evidence of police action in dealing with them.
I am fully aware that it's not 1829 anymore. But as one looks at the struggles of police forces across the country, it feels like time to restore and revivify the spirit behind a number of these principles.
