A Denver woman has filed a federal civil-rights lawsuit against Flock Safety and the Columbine Valley Police Department, alleging that police used license-plate camera data to track her and wrongly accuse her of theft. Chrisanna Elser says a Columbine Valley officer came to her Denver home in September 2025 and accused her of stealing a $25 package in Bow Mar, a community bordering her neighborhood. The court summons issued in the case was later voided, according to the account of the incident. The lawsuit alleges the department used Flock cameras to monitor Elser’s movements and that her attempts to show she was innocent were disregarded. It argues that the surveillance violated her rights and asks the court to require safeguards for the department’s use of the cameras. The claims have not been resolved in court. Elser said she brought the case to alert people to how license-plate tracking systems are used. She argued that even people who have done nothing wrong can be affected by the technology and its use in police investigations. Flock said its system correctly identified the location of Elser’s vehicle, while police were responsible for interpreting that information in the broader investigation. The company said it stands by the accuracy and integrity of its technology. Columbine Valley said it had not been served with the lawsuit and would not comment on pending litigation. Bow Mar directed questions to the police department. The officer involved, who remains a sergeant with the department, had not responded to a request for comment. The case comes amid broader debate over automated license-plate readers, which law enforcement agencies use to search for vehicles while privacy advocates warn the systems can enable extensive tracking. Defendants have up to three months to respond to the lawsuit.
