Public Records - As enacted, designates records of the office of homeland security related to critical infrastructure as confidential and exempts such records from public records requests; makes related changes. - Amends TCA Title 10, Chapter 7, Part 5.

SB 1881 would make certain records held by Tennessee's Office of Homeland Security about critical infrastructure confidential, preventing public access through standard public records requests. Specifically, it exempts three types of records: security analyses and warnings for infrastructure systems (like power grids or water facilities), threat prevention and defense efforts, and any records designated by the agency as relating to critical infrastructure. This bill amends Tennessee's public records law (TCA Title 10, Chapter 7, Part 5) to add these specific exemptions. The change directly affects the public's right to access this information and the Office of Homeland Security's disclosure obligations.
