Investigative Interviewing


Investigation is a core duty of law enforcement agencies. Interviewing victims, witnesses and suspects is central to the success of an investigation and the highest standards need to be upheld.

Agencies need to develop and maintain a valuable resource of a skilled interviewers. Interviews that are conducted professionally realise several benefits.

In particular, they can:

  • Direct an investigation and gather material, which in turn can lead to a prosecution or early release of an innocent person
  • Support the prosecution case, thereby saving time, money and resources
  • Increase public confidence, particularly with witnesses and victims of crimes who come into direct contact with law enforcement.

The PEACE model of investigation is widely recognised as the most effective and is used widely by law enforcement. This model allows the interviewer to carefully plan and prepare each interview in a structured format.
