Denver's City Council has voted unanimously to end its $666,000 contract with Flock Safety, the company behind the city's automated license plate reader system. The high-tech surveillance tool helped recover 170 stolen cars and led to 300 arrests, aiding investigations into serious crimes like hit-and-runs and homicides.

So why end it?

City leaders cite growing concerns about federal immigration enforcement, especially the possibility that ICE could use the data to track and deport undocumented immigrants. The move has sparked major controversy — critics say the council is putting immigration politics above public safety, while supporters argue it's about protecting civil liberties in an era of aggressive federal surveillance.
