Expanding the office of independent investigations to include prosecutions of criminal conduct.

HB 1740 expands Washington's Office of Independent Investigations to include prosecuting criminal cases related to officer use of force, directly affecting victims of such incidents and county prosecutors. The bill grants the office concurrent authority with county prosecutors to investigate and prosecute use-of-force cases and related offenses, while requiring the independent prosecutor to meet strict appointment criteria (including background checks for bias) and keep victims informed of case progress. It mandates public reporting when charges are declined for fatal use-of-force cases and clarifies cost responsibilities (the office covers its prosecution costs but not defense costs). The independent prosecutor, appointed by the director, holds final authority over charging decisions and case management within the office's jurisdiction.
