Four Flock cameras along the city's main highways, including one on East Main Street that was recently damaged and one near Benton Consolidated High School (Southern Illinoisan, Aug. 12, 2026).
  1. Aug. 2026 The Benton Police Department put a new policy in place governing how officers may access and use Flock camera data, with accountability for misuse. Images are kept 30 days. Officers ran 26 Flock searches between July 8 and Aug. 8. (The Southern Illinoisan, Aug. 12, 2026)
Conflicts and open questions
  • The article (Aug. 12, 2026) does not say when the policy took effect, so the event is dated to the month. Chief Chris Funkhouser said the cameras have helped in cases including missing people, stolen vehicles, homicides and sexual assaults.

  1. Jan. 1, 2020 The Tamara Clayton Expressway Camera Act took effect, creating the Illinois State Police plate-reader program on Cook County expressways. It is named for a woman shot on I-57 near Cicero Avenue on Feb. 4, 2019. (Illinois State Police, Division of Criminal Investigation, 2026)
  2. June 6, 2022 Gov. JB Pritzker signed an extension of the expressway camera program; the state police page lists $20 million from the IDOT Road Fund tied to that extension. (Illinois State Police, Division of Criminal Investigation, 2026)
  3. Aug. 11, 2023 Gov. Pritzker approved HB 3326 (Public Act 103-0540), effective Jan. 1, 2024. It bars plate-reader users from sharing data with any jurisdiction to investigate or enforce laws restricting reproductive or other lawful health care or allowing detention based on immigration status, requires out-of-state police to sign a written declaration before getting Illinois plate data, and treats the data as confidential. Capitol News Illinois reported the law sets no specific penalties. (Illinois General Assembly, Aug. 11, 2023; Capitol News Illinois, Aug. 27, 2025)
  4. March 2025 U.S. District Judge Martha Pacold dismissed Scholl v. Illinois State Police, a suit by two Cook County residents filed in late May 2024 against the state police, the governor and the attorney general, finding the expressway plate readers do not trigger Fourth Amendment scrutiny. (Date: the Monday before an April 4, 2025 report.) (WBEZ / Chicago Sun-Times, June 3, 2024; Chicago Sun-Times (via NPR Illinois), April 4, 2025)
  5. June 11, 2025 The Secretary of State's office met with Mount Prospect police and audited the village's Flock data, finding a May 9, 2025 nationwide search by a Johnson County, Texas, sheriff's office and 262 searches citing immigration between mid-January and April 2025. (Village of Mount Prospect, date not shown; Associated Press (via 6abc), June 13, 2025)
  6. June 12, 2025 Secretary of State Alexi Giannoulias asked the attorney general to review the Mount Prospect case and announced an audit system for compliance with the 2023 law. At his request Flock blocked 62 out-of-state agencies and began flagging 'abortion' and 'immigration' in search requests. (Associated Press (via 6abc), June 13, 2025)
  7. June 30, 2025 HB 3339 was signed, adding Lee, Ogle and Whiteside to the 20 counties already authorized for state police expressway cameras, allowing use in human-trafficking and involuntary-servitude investigations, and exempting camera images from FOIA. It took effect immediately. (Illinois Senate Democratic Caucus, June 30, 2025; Illinois State Police, Division of Criminal Investigation, 2026)
  8. Aug. 25, 2025 Giannoulias said an audit of a sample of 12 law enforcement agencies found Flock lacked proper data-sharing safeguards and had run a pilot giving U.S. Customs and Border Protection access to Illinois camera data. He ordered Flock to cut off that access; Flock paused its federal pilot programs nationwide. (NBC Chicago, Aug. 25, 2025; Capitol News Illinois, Aug. 27, 2025)
  9. Aug. 27, 2025 Capitol News Illinois counted about 90 Illinois police departments confirmed as Flock users; disclosures from 14 of them listed more than 461 Illinois agencies and 551 out-of-state agencies with access to their data. (Capitol News Illinois, Aug. 27, 2025)
  10. Sept. 5, 2025 Giannoulias reported that an audit found Forest Park police plate data from Motorola Solutions readers had been shared with federal immigration authorities, and directed Motorola to turn off sharing with federal agencies. (Forest Park Review, Sept. 5, 2025)
  11. Feb. 10, 2026 Rep. Kelly Cassidy introduced HB 5151, the Automated License Plate Recognition System Act, later sponsored by Rep. Nicolle Grasse. It would require police to delete plate data not tied to an investigation, court order or case within three days and would bar using the data to track people at protests, people seeking lawful health care, or for immigration enforcement. (Shaw Local, May 29, 2026)
  12. Sept. 29, 2026 A Seventh Circuit panel (Chief Judge Michael Brennan, Judges Rebecca Taibleson and Amy St. Eve) heard the appeal in the Scholl case. (Courthouse News Service, Sept. 29, 2026)
