When mass shooter Audrey Hale, deceased, planned to shoot up a Christian school in Nashville, she wrote a manifesto.

Weeks after the massacre of six people, including three children, it’s still being concealed.

And the Wisconsin Institute for Law & Liberty, in one of the cases seeking its release, is asking a court for an order that the FBI release at.

WILL said it wants the FBI to allow access to the manifesto by Hale, and has filed a motion for summary judgment in federal court in Nashville.

It’s one of several court cases seeking the release of the document.

“Hale’s motivations for the March 27 attack remain unknown to the public, and the FBI is illegally concealing the information in violation of the Freedom of Information Act,” WILL charged.

Deputy counsel Dan Lennington explained, “Transparency is the key to accountable government. The FBI unfortunately is resisting its legal obligations under FOIA, and we now have asked the court to order the release of the manifesto. We are happy to represent hardworking journalists that want to report on what happened and how we can make our schools safer.”

WILL’s client is The Star News Network, which is based in Nashville and continues to investigate the motivation of the shooter.

The FBI has denied access to the manifesto, and so WILL sued.

WILL is now filing for summary judgment, the organization said, explaining, “The FBI’s blatant refusal to release the manifesto is a violation of the law, and restrains the public’s right to know what happened and how we can keep our schools safe.

WND has reported that the Tennessee Firearms Association also has gone to court seeking access to the document created before Hale stormed the private Covenant Presbyterian School and killed six.

The firearms organization is demanding that the Metropolitan Nashville Police Department release the document.

That case explains, “[The Police Department] knew that the requested records were public and refused to disclose them.”

“We believe under the Tennessee Open Records Act that it’s not a question of will the manifesto be disclosed, but why have government officials stopped the release and how long will it take a court to address why that nondisclosure should be vacated and the government ordered to disclose the records,” explained TFA chief John Harris.
