To Whom It May Concern:

Pursuant to the Illinois Freedom of Information Act (5 ILCS 140/1 to 11), I hereby request the following records:

Documents sufficient to show:
1. The algorithm that determines who makes it on the strategic subjects list (hereafter, "the algorithm);
2. Descriptions of all variables in the algorithm;
3. The ways in which names are found to run through the algorithm and how often this is done;
4. The frequency on which the algorithm (e.g. twice a day; once a week; continuously each time names are added, specifying the frequency of running names)
5. The frequency with which names which have been run through the algorithm previously are run through again
6. Who (or employees of what company) wrote the algorithm
7. All contracts and invoices to/from the company that wrote the algorithm, or other records of purchase
8. The date when the algorithm was first administered or run on a regular or non-testing basis
9. Data sufficient to show names (or if names are required redacted by law, we request a column of unique identifying numbers) and risk scores of all people added to the list in its first two years of regular or non-test use. If this data set, in the format possessed by the requestee, includes a designation of each person's race, the information on race is requested to be included.
10. Data sufficient to show whether the first 5,000 people, as identified in (9), were charged with new crimes in the two years following their inclusion on the list. If this data set includes a designation of the charge, the information on charges is requested to be included.
11. All material about the risk scoring system and the data that is used to determine risk scores. This includes but is not limited to material sent from the company that provided (or provides) the services to Chicago Police Department. This includes but is not limited to all marketing publications and emails from the company to the department; training manuals; and consultation after the purchase of the product.

The requested documents will be made available to the general public, and this request is not being made for commercial purposes.

In the event that there are fees, I would be grateful if you would inform me of the total charges in advance of fulfilling my request. I would prefer the request filled electronically, by e-mail attachment if available or CD-ROM if not.

Thank you in advance for your anticipated cooperation in this matter. I look forward to receiving your response to this request within 5 business days, as the statute requires.

Sincerely,

Brandon Smith
