Firn in part asked:
The PEACE method seems to force the investigator to underweigh the power of confessions. An interesting question to more knowledgable guys out there: Does the greater quality and quantity of physical evidence (forensic science, information technology like cellphone location etc, etc...) make the PEACE approach more attractive and efficient relative to REID? If so in which cases?
It might help if you peruse this rather clear explanation of the policy and procedure:http://www.sussex.police.uk/policing...viewing-policy

The whole premise of the PEACE method for interviewing suspects is that they will give an account and if they do the account can be tested by referring to the evidence gathered.
