Senate Bill 1588 establishes a "capitol hill protection zone" around the state capitol grounds in Tennessee, which encompasses several key government buildings, including the state capitol, capitol annexes, and the Supreme Court Building, among others. This new part added to Tennessee Code Annotated, Title 4, Chapter 8, aims to enhance security measures in the area by ensuring that it is adequately staffed with law enforcement officers.

The bill mandates that the commissioner of safety is responsible for staffing the capitol hill protection zone with certified law enforcement officers who have concurrent authority with local agencies. These officers must complete additional training focused on laws regulating protests on state property and best practices for managing large public gatherings. The act is set to take effect on January 1, 2027.
