Controversy over release of Nashville school shooter's writings intensifies.

The Covenant School in Nashville, where a trans shooter killed six people, has filed to intervene in a lawsuit seeking the public disclosure of the shooter's manifesto. The National Police Association and a private investigator are suing city and county officials, demanding copies of Audrey Hale's writings. The police group said The Covenant School is asking to protect floor plans of its facility and personnel information. The killer wrote a manifesto, kept journals and made hand-drawn maps and diagrams of the school, with possible entry points and illustrations that depicted a shooter wearing the same outfit that Hale wore on the day of the shooting.
