Summary of the impact

This research, which examines police investigatory methods to identify police suspects has directly increased suspect identification rates by the Metropolitan Police Service (MPS). It led to the MPS establishing a register of `super-recognisers' - officers particularly skilled at identifying faces from CCTV footage - and changed practices. Dissemination of the research, also well-publicised in the media, has influenced national policy makers. There is worldwide interest and secured European funding for a test to identify super-recognisers amongst police cohorts. The research is also improving recognition of EFIT-V images, the facial composite system used by most UK police forces. Dr Davis is disseminating his findings through the training course that operators have to complete to be certified to produce composites in real police investigations. He is also contributing to economic impact by enhancing the EFIT-V product.

Summary of the impact

The development of a robust criminal justice system is vital in any civilised society and benefits victims, witnesses, police, suspects, and the general public. Research in the Department of Psychology at Royal Holloway, University of London has investigated fundamental principles underlying memory retrieval in the context of criminal justice scenarios in which memory may be particularly vulnerable. This research has had major impacts on the way in which police interview witnesses to a crime, and on the way in which video identification parades are conducted. It has also led indirectly to significant developments in the way in which evidence from very young children is treated in court.

Summary of the impact

The Self-Administered Interview (SAI©) is a powerful evidence-based investigative interviewing tool designed to elicit comprehensive initial statements from multiple witnesses and victims, particularly in time- and resource-critical situations. Developed in the laboratory and tested in the field, the research underpinning the SAI© has resulted in changes in policy, professional practice and training activities within police forces internationally. Operationally, the SAI© has contributed to the investigation of major criminal incidents enabling investigators to collect information from witnesses in challenging situations. The SAI© has elicited critical leads and compelling evidence for Court proceedings — indicating public benefit arising from service improvements.

Summary of the impact

The University of Portsmouth research into effective use of the Cognitive Interview (CI) by police forces in the UK and overseas has led to recommendations for changes to training of police officers in this field throughout their careers being adopted in several countries across the world. The work, led by Dr Becky Milne, has also been used to inform the decision making processes of a variety of national policy reviews and professional bodies. Research has improved the standard of interviewing, particularly for sensitive investigations such as rape and child abuse.

Summary of the impact

Changes to the law in the early 1990s removed the need for corroborating or physical evidence in abuse cases and allowed videotaped evidence of a child or other vulnerable witnesses to be used in a criminal court. This necessitated the drawing up of guidance to help police officers and other judicial practitioners, gather crucial evidence while minimising unintentional influence. Research at Leicester has underpinned work to assess and improve the effectiveness of this guidance and to create a framework of procedural best practice. This has influenced and directed the formation of protocols and training development of practitioners for uniform, fair and reliable investigative interviewing of vulnerable witnesses and for accurate identification and interrogative interviewing of suspects in the UK and through the sharing of best practice, across the UK and internationally.

Summary of the impact

Researchers at Abertay University are engaged in research that focuses on developing and testing evidence-based procedures that inform and enhance policing procedures surrounding evidence gathering. One particularly successful line of research has produced an innovative investigative tool called the `Self Administered Interview' (SAI©) that is proven to enhance witness statements and protect memory. The SAI© was developed and tested in a series of controlled lab-based studies at UAD, and later field-tested with eyewitnesses to real crimes with the support of the Association of Chief Police Officers. The SAI© is already standard police practice in some UK and European forces with over 2,500 officers trained in its use. It has also been used in major Health and Safety investigations in the off-shore Oil and Gas industry.

Summary of the impact

Frowd's research aims to understand the extent to which witnesses and victims of crime construct accurate facial composites (pictures of criminal's faces), and to develop techniques which maximize the effectiveness of composites, thus allowing the police to identify as many offenders as possible using this type of forensic evidence. The principal impact involves a software system (EvoFIT), a new interview (Holistic-Cognitive Interview, H-CI) and two formats (animated caricature and stretched composite) for the police to publish composites in the media. In the audit period, these advancements have been used by police forces in the UK, US, Romania and Israel.

Summary of the impact

Brookman's research has produced new insights into the nature and circumstances of homicide and homicide investigation. The first four pages on the Murder Investigation Manual, commonly viewed as the definitive guide on homicide investigation in Britain, are based on Brookman's research on the characteristics of homicide. The directives of the International Association of Chiefs of Police based in the United States (US) devote one or their top ten directives to Brookman's proposals on broadening outcome assessments. The Prince George's County Police Department in the US is currently considering implementing Brookman's proposals to include Family Liaison Officers as part of their process of homicide investigation.

Summary of the impact

This case study is based on the use of storytelling research developed in Sunderland, to develop professional practice, management development, and interviewing approaches within the police. The research and subsequent impact developed from the convergence of three separate streams of work: The exploration of storytelling as a means to management and organisational development (the work of Reissner and Du Toit), use of storytelling as a research method (Sanders and Lawson) and a stream exploring investigative interviewing techniques. Application of the approaches developed at Sunderland within the police force regionally and nationally has led to evidenced impact at several levels: individual officers, force development and national policy on interviewing practice.

Summary of the impact

This case study focuses on the researcher's work on witness protection arrangements put in place by police forces to ensure the safety of individuals and close relatives whose lives are in danger as a result of their willingness to give evidence in criminal trials. Typically this involves the permanent relocation of witnesses and their families to new communities and the adoption of new identities.

This research was the first of its kind in the world and its impact has been evident in:

• Changes in UK legislation with respect to witness protection arrangements;
• Changes in the organisation and delivery of witness protection in Scotland;
• Invitations to advise other jurisdictions on witness protection reform and to contribute to media and policy debates;
• Use of the research by police practitioners in the UK and internationally in the continuing professional development of police officers involved in witness protection programmes;
