The Principles on Effective Interviewing for Investigations and Information Gathering or the "Méndez Principles" aim to modify police practices by replacing coercive interrogations with rapport-based interviews.

 

Based on science, law, and ethics, the Méndez Principles propose a concrete alternative to interrogation methods that rely on coercion to extract confessions. They improve the results of investigations, fully respect human rights and enhance trust in the State.
