Documented Incident
Brookfield officials question Flock contract after erroneous alert leads to high-risk stop
First reported: August 10, 2026 · 13 sources
Brookfield, Wisconsin officials are reconsidering the city's license plate reader contract after police acted on a Flock alert for a vehicle tied to a Milwaukee homicide, conducting a high-risk traffic stop and detaining two people. According to the report, Milwaukee police had not removed the vehicle from the alert system. Alderwoman Catherine Kahler said on Facebook and in a Monday email that she no longer supports the program, citing government collection of movement data on law-abiding people through a private company and its larger network. Alderman Peter Stoll said the concerns are legitimate but that he has not decided and wants more information from the police chief and colleagues.
The episode illustrates how a stale entry in a shared alert database can produce a felony-level stop of people not suspected of wrongdoing, and how such errors can prompt local councils to revisit surveillance contracts they previously approved.
Key facts
- TMJ4 obtained the contract: a two-year, $40,000 agreement covering seven Flock cameras in Brookfield.
- Brookfield officers detained two people during a high-risk stop; the vehicle had reportedly not been removed from Milwaukee police's alert list.
- Alderwoman Catherine Kahler said she now opposes continued participation; Alderman Peter Stoll said he remains undecided.
- A Flock spokesperson said agencies own and control their data, access is limited to authorized users, and data is deleted after 30 days unless retention is requested.
- Flock said its Wisconsin cameras alerted authorities to 16 missing people and more than 200 sex offenders in July alone; the figures come from the company.
