Reporters and lawyers warn lawmakers that networked commercial surveillance can bypass oversight and chill constitutional rights

At a California Assembly informational hearing, investigative reporter Jason Kebler and law professors urged lawmakers to confront how private surveillance infrastructure — from license-plate readers to doorbell cameras and analytics vendors — can be repurposed by law enforcement and third parties in ways that evade existing constitutional protections.

"Local citizens become guinea pigs for things like autonomous drones, license plate reader technology," Kebler said, describing patterns where surveillance startups deploy discounted pilot programs to police departments and later leverage network effects to scale statewide or nationally. Kebler described public-record findings that some cross-jurisdiction searches were conducted for immigration enforcement and other improper purposes, and that police often lacked clarity on vendor contracts and network sharing.

Professor Nila Bala (UC Davis) told the committee the Fourth Amendment and the third-party doctrine are ill suited to the data ecosystem, where location, health, and browsing information passes through intermediaries and can be acquired without a warrant. She proposed possible legislative responses including statutory categories that are off-limits in criminal investigations, deletion mandates, and a "digital evidentiary privilege" that would bar certain classes of privately collected data from court evidence.

The committee discussed enforcement tools such as suppression remedies (discussed in CalECPA) and private rights of action; witnesses noted that California law already provides stronger foundations than many states but that enforcement resources and statutory clarity remain lacking. Lawmakers asked for drafting guidance to avoid overbroad definitions that would unintentionally block beneficial safety uses, and panelists urged robust auditing and public transparency for government contracts with vendors.

No formal action was taken during the hearing. Committee members said they will use reporting and legal proposals presented at the hearing to inform possible statutory language, enforcement design, and discussions about jurisdictional limits on the use of commercially collected data.
