when are police required to administer the miranda warnings
Miranda warning The duty to warn only arises when police officers conduct custodial interrogations. The Constitution does not require that a defendant be advised of the Miranda rights as part of the arrest procedure, or once an officer has probable cause to arrest, or if the defendant has become a suspect of the focus of an investigation. Custody and interrogation are the events that trigger the duty to warn.
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]
