Based on reporting and open records from other ACLU affiliates over the past few years, we know that ICE has gained access to troves of data from sanctuary cities to aid in its raids and immigration enforcement actions, including data from the vast network of automated license plate readers (ALPRs) across the country.
Expanding the use of this technology in Wisconsin raises concerns about ALPR surveillance data being used to target individuals seeking reproductive healthcare, gender affirming care, and protesters engaged in activity protected by the First Amendment.
In May 2025, 404 Media reported that local police around the country are performing lookups in Flock’s AI-powered ALPR system for “immigration” related searches and as part of other ICE investigations, giving federal law enforcement side-door access to a tool that it currently does not have a formal contract for.
