what is the role of law enforcement in the criminal justice system
Criminal justice The first contact a defendant has with the criminal justice system is usually with the police (or law enforcement) who investigate the suspected wrongdoing and make an arrest, but if the suspect is dangerous to the whole nation, a national level law enforcement agency is called in . When warranted, law enforcement agencies or police officers are empowered to use force and other forms of legal coercion and means to effect public and social order. The term is most commonly associated with police departments of a state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility. The word comes from the Latin politia ("civil administration"), which itself derives from the Ancient Greek πόλις, for polis ("city").[7] The first police force comparable to the present-day police was established in 1667 under King Louis XIV in France, although modern police usually trace their origins to the 1800 establishment of the Marine Police in London, the Glasgow Police, and the Napoleonic police of Paris.[8][9][10]
Criminal justice ethics The United States has various laws and policies in place, such as the Miranda Rights, that are meant to ensure ethical practices by law enforcement officials. Further measures have been adopted to secure ethical standards in police departments.[2] Such measures include various codes of ethics provided by professional law enforcement associations like the Law Enforcement Code of Ethics, adopted in 1957, and the American Federation of Police, adopted in 1966.[2] The Law Enforcement Code of Ethics was revised in 1989 by the International Association of Chiefs of Police.[2][14] The U.S. does not have a national code of ethics, rather individual police departments construct their own code of ethics based upon the basic standards laid out in the law enforcement associations that are then incorporated into an oath of office each member of the department pledges.[2]
