The focus of this Protocol is the independent investigative process of officer involved deadly force incidents, both criminal and administrative. The integrity of deadly force investigations is the guiding principle in all decisions.  This Protocol is not intended to alter or interfere with any agency’s employer-employee relationship reflected in statute or a collective bargaining agreement.  Any relevant statutes, case law ruling, department rules and/or policies, or contents of a collective bargaining agreement shall take precedence over this Protocol should the contents of this Protocol conflict.


This Protocol addresses the potential for one of the agency’s officers becoming involved in a deadly force incident, either within or outside of their jurisdiction.  This Protocol, in compliance with WAC 139-12-010 and RCW 10.114.011, calls for the use of outside personnel to conduct an independent investigation into officer involved deadly force incidents.


This Protocol and the related procedures are presented for your consideration.  It is believed they are sound and take into consideration the major concerns related to officer-involved deadly force incidents and their investigation. Permission is hereby granted to law enforcement agencies in other regions to copy, use, modify, or alter them as needed to address the needs of their region or jurisdiction.
