Using the PEACE model for witness interviews


Why do we interview?

  • to gather accurate and truthful information

  • to get answers to the 5W's (Who, what, when, why, where) & How

  • to open up further lines of enquiry

This is a BASIC overview of the PEACE model of interviewing, what it means, how it can be used to great effect and how to implement these practices into your witness interviews.

We will explore the differences in Open and Closed questions, and how to get the best out of your witness, even information they didn't think THEY knew!
