This bill aims to enhance public safety by promoting evidence-based interview practices in law enforcement, specifically by implementing rapport-based, noncoercive techniques instead of deceptive tactics during interrogations. The legislature recognizes that these methods lead to more accurate and reliable information from suspects and witnesses, thereby fostering public trust and cooperation with law enforcement. The bill outlines the importance of training law enforcement personnel in these techniques and establishes a framework for their implementation.

Key provisions of the bill include a presumption of inadmissibility for statements obtained through deception during interrogations, effective from December 31, 2026, unless the prosecution can prove the statement was voluntary. Additionally, the bill mandates the development of a comprehensive training program for law enforcement on evidence-based interrogation techniques, which must be made available at no cost to all personnel and agencies in Washington State by July 1, 2026. The training will cover various methods, including the PEACE method, cognitive interviews, and trauma-informed interviews, to reduce the risk of false confessions and improve investigative outcomes.
