On Thursday, Flock announced plans to require all agencies with access to license plate reader data to use a safety tool that automatically detects abnormal activity and locks out cops who abuse their access to stalk people they know in their personal lives.

Flock’s audit assistance tool suspends access when user activity “meets defined criteria for abnormal behavior,” Flock said. The suspension can only be lifted by administrator review, with the goal being “to intervene before misuse becomes recurring or widespread.”
