Flock Safety will require all agencies using its number-plate reader data to activate an auditing tool designed to detect unusual searches and suspend officers suspected of misusing the system. The move follows cases in which police officers allegedly used Flock cameras to stalk acquaintances, but civil-liberties experts say technology alone cannot guarantee accountability or prevent agencies from concealing misconduct.

The tool had been optional since April, with only about one-third of agencies adopting it; a Georgia sheriff’s office using it arrested three officers in separate alleged stalking cases. Flock says abuse reports rose predictably where the tool was enabled, but the ACLU says there is no independent evidence that it reliably identifies misuse and calls for external evaluation and transparent reporting. Former San Francisco district attorney Chesa Boudin said meaningful consequences depend on local agencies’ willingness and legal ability to discipline or prosecute officers.
