Modernizing, harmonizing, and clarifying laws concerning sheriffs, chiefs, marshals, and police matrons.

SB 5364 standardizes requirements for Washington sheriffs, police chiefs, and marshals by mandating state law enforcement certification within 12 months of appointment, background checks, and consistent eligibility criteria (including high school diplomas, no felony convictions, and meeting peace officer training standards). It clarifies that volunteers in law enforcement agencies may assist with non-enforcement roles (e.g., search and rescue) but cannot carry weapons or make arrests without certification. The bill repeals outdated "police matrons" provisions and reinforces that sheriffs’ core duty is enforcing state law as interpreted by courts. These changes apply to all cities and towns with law enforcement agencies across Washington.
