Police officers used Flock Safety cameras to track exes and other personal targets. Flock’s security chief explains what its cameras record, who can search the data, and what the company says is changing now.

In this episode, Frank Downs and Dr. Dustin Brewer sit down with Chris Castaldo, Chief Information Security Officer at Flock Safety, for a direct conversation about the nationwide license-plate-reader network appearing along roads, in neighborhoods, and outside private businesses.

Chris previously worked in the NSA’s Tailored Access Operations, served in the U.S. Army during Operation Iraqi Freedom, and is the author of Startup Secure.

The conversation covers:

• Officers accused of using license-plate searches for personal tracking

• Flock’s announced reduction of its default retention period from 30 days to seven days for new customers

• Anomalous-search detection, account lockouts, case numbers, and audit controls

• Why multi-factor authentication only recently became mandatory

• What a Flock camera records when a vehicle passes

• How the image travels from the roadside camera to cloud storage

• How law-enforcement agencies, businesses, and HOAs can share camera observations

• Who Flock says owns the data and who can search it

• Whether Flock cameras collect Wi-Fi, Bluetooth, or phone identifiers

• The separate Flock camera feeds exposed through a cellular-provider configuration issue

• The absence of a comprehensive federal privacy law governing this technology

• Whether Flock plans to add facial recognition

• How some vehicle images may be used for machine-learning training

• The public-safety argument involving stolen vehicles, missing people, and AMBER Alerts

• Whether Frank and Dustin’s opinions changed after hearing Flock’s answers

The central question is not whether this technology can help solve crimes. It can.

The question is whether a system powerful enough to help locate a missing child is also powerful enough to expose the movements of innocent people—and whether companies, police departments, lawmakers, and oversight systems can keep up.
