A conversation between an investigator and victims, witnesses, and suspects intended to elicit information. The nationally accepted model of investigative interviewing has five phases and is usually referred to by the acronym PEACE. See also cognitive interview; conversation management.
The questioning of suspects is sometimes termed interrogation, although there are negative connotations associated with the term. Suspects are not obliged to answer such questions (see right of silence), and the right of the police to question suspects is governed by the Police and Criminal Evidence Act 1984 and the Codes of Practice made under it. The Codes deal with such matters as the rights of the suspect to communicate with third parties, rights to legal advice and to medical treatment, and advice to the police on the administering of a caution, the provision of interpreters, and the keeping of records concerning all these matters. There are special provisions applying to interviews with juveniles, the mentally ill, and the mentally handicapped. The provisions of the 1984 Act and its Codes must now be read subject to the requirements of the Human Rights Act 1998. See also confession.
