was to obtain a confession from a suspect in order to secure a conviction. Thus, investigative interviewing contrasts pervasive interrogations techniques aimed at making the suspect break down and confess. The stark difference between these two approaches to police interviewing has led some authors to argue that the term "interrogation" should be scrapped altogether as it is inherently coercive and aimed at obtaining a confession.

In the interim report dated 5 August 2016 to the UN General Assembly of the
special rapporteur on torture and other cruel, inhuman or degrading treatment or punishment,
Juan E. Méndez, the investigative interviewing method is presented at length as an example of best practice.
Since the implementation of cognitive interviewing, this technique has undergone significant changes. These changes have enhanced the process of memory recall in various law enforcement investigations. (1) The development of structured protocols has made cognitive interviews more systematic. Beyond the rapport building, and open-ended questions, it encourages the witness to visualize the event enhancing memory recall. This structure helps reduce bias and increases the reliability of the information gathered. (2) Advancements in recording technology have allowed interviews to be documented more accurately. Video and audio recordings provide a reliable reference that can be reviewed later for analysis, ensuring that the details are not lost or misinterpreted. (3) Cognitive interview techniques have evolved for use with different populations, including children and individuals with cognitive impairments. Tailoring the approach to meet the needs of various witnesses ensures that all voices can be heard effectively. (4) Enhanced training programs for law enforcement personnel have been developed to ensure that interviewers are skilled in applying cognitive interview techniques. Standardized training helps maintain a high level of competency across different departments and regions. These improvements have contributed to making cognitive interviews a more effective tool in gathering accurate eyewitness testimonies, ultimately leading to better outcomes in investigations.

United Kingdom
The PEACE model (Preparation and Planning, Engage and Explain, Account, Closure and Evaluate) for police interviewing was developed in the United Kingdom in response to a number of documented forced confessions and associated wrongful convictions in the 1980s and 1990s. Most notable were the cases associated with the conflict (

Norway
Investigative interviewing was adapted by the Norwegian police in 2001. The acronym used for the training programme for the Norwegian police is KREATIV (or CREATIVE in English) and is composed of phrases reflecting the values and principles upon which the method is based. These are; Communication; Rule of Law; Ethics and empathy; Active awareness; Trust through openness/transparency; and Information. The "V" stands for Science ("Vitenskap" in Norwegian, "Wissenschaft" in German), referring to the method's foundation in research. Professor
