Read more about the checklist

Peer-reviewed by leading experts in the field of investigative interviewing, this tool aims to uphold both effectiveness and ethical standards in investigations, making it an essential resource for professionals and students alike. This checklist is designed for those familiar with investigative interviewing. Limited in its format (only 1 page), it should serve as a visual reminder to ensure critical steps and considerations are remembered and followed.

"Having a checklist like this is a central pillar in ensuring that effective interviewing practice is maintained and implemented across the globe. A handy reminder for all; those new to this way of working and those seasoned with using appropriate practice—everyone needs a clear user-friendly guide." — Professor Rebecca (Becky) Milne. 

The checklist is available in English and Portuguese, and forthcoming in Icelandic, Ukrainian and Norwegian. 

Vulnerability guidelines

When conducting interviews, police officers frequently encounter individuals who may be considered vulnerable. Some of these individuals face specific challenges that must be carefully addressed to ensure they are not placed at further risk and are able to fully exercise their procedural rights.

Interviewers must work carefully—through preparation and rapport building – and indeed before, during and after the interview - to reduce the impact of these vulnerabilities and create the safest and most supportive interview environment possible.

The guidelines for assessing vulnerability during criminal investigations, police interviews and criminal proceedings are designed as a practical tool to assist police officers and other professionals who conduct interviews. The guidelines were originally developed for Belgian defence lawyers by Professor Lore Mergaerts (KU Leuven).

These guidelines aim to deepen understanding of what vulnerability entails and how it may present itself in an interview context. They may support interviewers in identifying potential vulnerabilities - but more importantly - they can serve as a learning tool giving some substance to the issue of vulnerability.

Additional resources

All these tool and resources align with the ethos of Investigative interviewing, a non-coercive, research-based, human rights compliant and effective method for interviewing victims, witnesses, and suspects. It provides police and intelligence officers with reliable, accurate and actionable information. In criminal investigations it contributes to retrive evidence that stand the test of trial. In addition, long-term positive effects include de-escalation of violence; improved background intelligence; trust building between law enforcement and citizens; and in turn enhanced state legitimacy.
