Flock cameras, and other license plate reader systems, are installed all over Colorado. The technology gives law enforcement access to a new level of tracking, a reach they say has helped them solve all kinds of terrible crimes and made the state safer. But community fears that law enforcement could misuse the data and invade people’s privacy, and share it with federal immigration authorities, are mounting — and getting the attention of state lawmakers. 

CPR’s Bente Birkeland and Denverite’s Andrew Kenney dig into how this kind of surveillance tech has changed in recent years, the arguments for and against it and how some Colorado lawmakers hope to restrict how law enforcement can access this data.
