To Whom It May Concern:

Pursuant to the Tennessee Public Records Act, I hereby request the following records:

Investigative centers around the country use Palantir, a data aggregator. ( Palantir has a software called "Gotham" which is often used by law enforcement. (

Therefore, I am requesting the following records related to Palantir:

* Any software and algorithms developed for the implementation of Palantir software, such as Gotham, in TBI activities. I'm particularly interested in any algorithms that have a public policy outcome, such as providing guidance on a policy or an assessment of an individual. More generally, I would like any software that was developed by or with, given to, used by, purchased or licensed to this agency for implementation of the above referenced program. This would include original source code, any compiled binaries (also known as executables), spreadsheets, program scripts, and other digital materials used to calculate any data in the above program. It would also include the input training data for machine learning algorithms.
* All instructional materials, presentations and presentation materials (including recorded video and audio, PowerPoint files, prepared remarks, and slides formats), and other guidance on the use of Palantir/Gotham. This includes any notes taken during meetings that discussed the use of Palantir/Gotham, any explanations (whether internally or externally generated) of how Palantir/Gotham works, and any other document that has been used to help explain the use of Palantir/Gotham to any party, including internal documentation, public relations materials, and executive summaries. This also includes any description of input and output data fields that will aid in understanding the type of information that is submitted to Palantir/Gotham, and that is produced by Palantir/Gotham.
* A copy of any privacy impact assessments, use policies, standard operating procedures, data retention policies, legal opinions, warranties, non-disclosure agreements, contracts, liability waivers, insurance agreements, Requests for Proposals, Responses to Requests for Proposal, Memorandums of Understanding, Letters of Interest, usage policies, or informal agreements that reference "Palantir" or "Gotham" or otherwise guide it use or the relationship between this agency and the provider or developer of Palantir/Gotham.
* A copy of any funding opportunity announcements, grant applications and grantor status/progress reports, reports to legislative bodies, annual reports that mention the use of Palantir/Gotham, as well as audit records, including but not limited to security audits of Palantir/Gotham, misuse reports, and reports to oversight bodies.
* A copy of any validation studies conducted with respect to Palantir/Gotham in TBI activities or with respect to any software or algorithms used in connection with Palantir/Gotham in TBI activities, and a copy of any records pertaining to inquiries for the need of validation studies, or discussion of potential or actual validation studies. By “validation study,” I mean any study designed to assess how accurate Palantir is in predicting what it is supposed to predict, or to assess whether Palantir may err in the direction of either under- or overestimating likelihoods or predicted outcomes, or may produce any results that are biased or unexpected in any way.
* For the aspects of Palantir/Gotham that require an input, for example, to compute a value, we request a copy of the five most recent sets of data that were used for input, as well as the five most recent outputs of Palantir/Gotham, in whatever their native format is. If these inputs or outputs include exempt information, we ask that you exempt only that information which is specifically exempted from law, and provide the other material.
* Any electronic mail communications and electronic mail attachments that mentions "Palantir" or "Gotham." Please limit the search results from January 1, 2012 to present.
