The bill establishes a Local Law Enforcement Grant Program aimed at enhancing public safety funding for local and tribal law enforcement agencies in Washington State. It introduces a new section to chapter 43.101 RCW, which outlines the program's framework, including the criteria for grant eligibility, application procedures, and the types of expenses that can be covered by the grants. Agencies must demonstrate compliance with various policies and training requirements to qualify for funding, which can be used for hiring, training, and retaining law enforcement personnel, as well as for broader public safety initiatives. The program is funded through a newly created Supplemental Criminal Justice Account, which will receive appropriations and other funds specifically for this purpose.

Additionally, the bill allows qualified cities and counties to impose a local sales and use tax to support criminal justice purposes, contingent upon meeting specific requirements related to the grant program. This new section added to chapter 82.14 RCW outlines the process for implementing the tax, including the need for voter approval if not adopted by local authorities by a specified date. The tax revenue must be used for activities that support the criminal justice system, such as domestic violence services, public defender staffing, and diversion programs. The bill includes provisions for reporting and accountability to ensure that funds are used effectively to improve public safety.
