A pattern is emerging across the country: police departments that installed Flock Safety license plate readers to catch stolen cars and hit-and-run suspects are now facing scrutiny for letting Immigration and Customs Enforcement tap into that same data to hunt for undocumented immigrants.

The clearest evidence comes from Shaker Heights, Ohio, where local reporting found that hundreds of immigration-related searches had run through the suburb's Flock camera system, according to Cleveland.com. Cleveland Scene reported that Shaker Heights changed its Flock policy after outside agencies used the network for immigration searches, and Cleveland.com and News 5 Cleveland WEWS both reported the city council subsequently restructured its Flock contract to block outside immigration searches and restrict federal access to the data. But according to Cleveland Scene, immigration activists said the "tightened" agreement still may not go far enough to address the underlying surveillance risk.

In California, Chico Police Department granted ICE and U.S. Border Patrol direct access to its ALPR data, according to KRCR and American Community Media. Chico city leaders are now reviewing whether that data-sharing arrangement was handled improperly, KRCR reported.

In the Twin Cities, Star Tribune and MinnPost investigations found that suburban Minneapolis-area police departments searched Flock cameras for immigration enforcement purposes during a federal ICE surge, according to both outlets, exposing federal use of local camera networks with little public transparency. MPR News reported that the surge coincided with aggressive ICE tactics against bystanders in the region. Following the reporting, Star Tribune reported that several Twin Cities suburbs moved to restrict access to their license plate data.

In California's Coachella Valley, the debate has played out publicly in Palm Springs, where the police department won approval for its Flock-powered data program despite concerns raised about ICE access, according to The Desert Sun. NBC Palm Springs reported that Police Chief Shaw responded to public privacy concerns by announcing new audit rules governing who can access camera data — part of a broader regional fight, chronicled by the Coachella Valley Independent, over whether the roughly eight of nine Coachella Valley cities running ALPR cameras are striking the right balance between public safety and civil liberties.

The pattern extends beyond individual departments. The Electronic Frontier Foundation reported that Flock Safety systems used by police agencies nationwide are comparing scanned license plates against hotlists built for ICE to locate immigrants — a practice Flock IT previously covered in "Police ALPR Systems Reportedly Comparing License Plates Against ICE Hotlists."

Some jurisdictions are responding with firmer rules rather than just contract language. Bloomington, Indiana updated its police department's Flock policy to formally codify an existing ban on immigration-related searches, according to Indiana Public Media and the Indiana Daily Student, which had also reported the department barring Flock data use in both immigration and reproductive-health investigations. That move follows sustained pressure from the ACLU's "Get The Flock Out" campaign and ACLU of Indiana's parallel effort urging cities statewide to drop Flock contracts entirely.

Taken together, the incidents in Ohio, California, Minnesota and Indiana show local ALPR networks built for routine policing increasingly functioning as feeder infrastructure for federal immigration enforcement — with communities only learning the extent of that access after journalists or advocacy groups force it into the open.
