CHICAGO · CONFIDENTIAL ANALYTICS SECTION

After 2020 protests, Chicago created a 20-person unit for round-the-clock social-media monitoring—and disclosure of how it worked required another lawsuit.

In August 2020, Chicago announced an expanded 20-person social-media monitoring effort following months of protests. CPD subsequently created its Confidential Analytics Section within the Bureau of Counterterrorism. According to records later obtained by the ACLU of Illinois, its mandate extended beyond looting or spontaneous gatherings to social-media use for any “valid law enforcement purpose.”

The ACLU sought records explaining the program. CPD resisted disclosure, at one point arguing that releasing information would create a clear and present danger. The litigation continued until CPD produced the previously secret policy and related materials after court orders; the ACLU reports CPD was found in contempt for failing to comply with earlier disclosure orders.

Why it matters: Surveillance of public speech can itself be difficult for the public to observe. Without reporting requirements, residents may know a monitoring unit exists while having no practical way to know whom it searches, how often, or what happens to collected information.
