The role of recording in police interviewing techniques 

In the ever-evolving landscape of policing and criminal investigations, the practice of recording interviews holds a pivotal role, bridging the gap between traditional police interview techniques and contemporary standards of justice and human rights. In the past, relying on notes or simply on the officers’ memory has been harmful not only to the interview, but also to its weight as evidence in court. 

In the UK The Royal Commission on Criminal Procedure in 1981 set out the problem which it faced in respect of the lack of recording of interviews as follows: 

“The frequency of challenges to the police record of interviews is said to make it essential to have some sort of independently validated record in order, in the eyes of some, to prevent the police from fabricating confessions or damaging statements, or, in the eyes of others, to prevent those who have in fact made admissions subsequently retracting them. It is the ‘verbals’ which give rise to most concern, that is the remarks which are attributed to the suspect in the police officer’s subsequent note of the interview but which the suspect is not prepared to endorse by making a written statement under caution. Indeed, it is argued by the Circuit Judges that the present methods of recording interviews are themselves the cause of a substantial number of acquittals of apparently guilty defendants. Many of our witnesses also point to the waste of court time caused by disputes about statement evidence.” 

The turning point came with the introduction of the Police and Criminal Evidence Act 1984 in England and Wales (PACE), which made it compulsory to use recording systems during all suspect interviews. This legislative milestone marked the beginning of a global shift towards standardising the digital interview recording, a practice supported by both technological evolution and a growing recognition of its necessity for upholding justice. Nowadays it is recommended as a best practice to record all interviews including the ones with victims and witnesses. 

Why record interviews? The cornerstone of justice and integrity 

Recording interviews serves as a fundamental safeguard against miscarriages of justice, ensuring that the words spoken by individuals during one of their most vulnerable moments in life are preserved accurately. This practice compensates for the shortcomings of human memory, reduces cognitive load on interviewers, and significantly enhances the communicative and methodological quality of interviews. By providing an accurate account of the interaction, recordings can protect both the interviewee from potential mistreatment and the interviewer from unfounded accusations. The presence of a complete and authentic record aids in the investigation of any allegations of ill-treatment and cultivates the ethical standards and integrity of the police force.  

The benefits of police interview recording extend beyond the immediate context of the interview room. Recorded interviews can be shared in real-time or after the fact, helping to share knowledge among the personnel, bringing in expert input and improving overall decision-making. Moreover, these recordings serve as invaluable tools for training, feedback, research and knowledge-development, ensuring the officers are equipped with the best practices in investigative interviewing.  

Implementing video recording: a step-by-step guide for effective policing 

Optimal results of the interview video recording can be achieved through detailed preparation, sound check procedures and the use of reliable equipment. High-quality recording systems that are easy to handle ensure consistency and integrity of the process. Recordings should be made without manipulation, with a focus on transparency and accountability. The use of digital signatures, reliable transferring and archiving procedures further safeguards preserving evidence and ensuring its court-ready evidence status. 

Navigating the obstacles 

Despite its clear advantages, the adoption of police interview recording is not without challenges. Training and motivating personnel, managing the transformation and storage of information, and ensuring compatibility across different systems are just a few of the hurdles to overcome. However, these obstacles are far outweighed by the benefits of increased accuracy, efficiency, reliability of testimonies, and the safeguarding of human rights. On top of that an experienced technological partner can help with implementation and training process to make the transition as smooth and bespoke as possible. 

In conclusion, the practice of recording interviews in policing and investigations represents a critical evolution in the pursuit of justice and ethical standards. As technology advances and international norms shift towards greater transparency and accountability, interview recording stands as a testament to the commitment to uphold the dignity and rights of all individuals within the criminal justice system. The global standard presented in Méndez Principles recommend recording of all the interviews and hopefully as the understanding of its importance grows – more countries will ammend their legislation and practices accordingly.  

For companies like Davidhorn, embracing and advocating for it is not just a recommendation; it’s a responsibility to the future of policing and the communities we serve.
