The ACLU complaint said Detroit police unthinkingly relied on flawed and racist facial recognition technology without taking reasonable measures to verify the information being provided." DataWorks Plus, a South Carolina company that provides facial recognition technology to Detroit and the Michigan State Police, also couldn't immediately be reached for comment.

HIGHLAND PARK, Mich. - The success of Project Greenlight in Detroit has two nearby cities looking to copy it. According to the Detroit News, Highland Park and Ecorse are set to install blue lights in city businesses. A $175,000 grant will help pay for 75 cameras in each city. The concept will be similar to Detroit's with cameras installed at gas stations and stores that will be monitored remotely. They will also be equipped with a public address system so people at the scene can talk to operators before police get there.
