In 2015 the U.S. Department of Justice issued a final report from the 21st Century Task Force on Policing. A core focus of that report addressed strategies for improving relationships, increasing community engagement, and fostering cooperation. The report recommended clear and comprehensive policies on the use of force, training on the importance of deescalation, crisis intervention and mental health, the provision of first aid, and recommended external and independent investigations in officer involved shootings resulting in injury or death. Initiative 940 and SHB 1064 incorporated those recommendations and these WACs implement the requirement of an independent investigation that is completely independent of the involved agency. The goal of this requirement is to enhance accountability and increase trust to improve the legitimacy of policing for an increase in safety for everyone.

Ultimately, this is about the sanctity of all human life; the lives of police officers and the lives of the people they serve and protect. The preservation of life should be at the heart of American policing. RCW 9A.16.040 provides a legal justification for officers whose use of deadly force meets the "good faith" standard. RCW 10.114.011 requires that where the use of deadly force by a peace officer results in death, substantial bodily harm, or great bodily harm an independent investigation must be completed to inform any determination of whether the use of deadly force met the good faith standard established in RCW 9A.16.040 and satisfied other applicable laws and policies. The independent investigation is conducted in the same manner as a criminal investigation and state law requires an "independent investigation" completely independent of the involved agency.
