One month of police-drone operations produced 537 videos—and a major privacy problem over what the cameras captured on the way to calls.

Chula Vista Police Department pioneered the 'Drone as First Responder' model, dispatching drones to selected 911 calls so remote pilots can stream video to officers before ground units arrive. Journalist Arturo Castañares sought all drone footage from March 2021 under the California Public Records Act.

The resulting litigation produced an unusually concrete picture of incidental collection. A city declaration stated that the request encompassed 537 videos totaling 91 hours, 39 minutes and 52 seconds. The city estimated that reviewing and redacting the material would require roughly 1,833 hours—or about 229 workdays—before legal review and quality control.

The California Court of Appeal agreed that the footage implicated serious privacy concerns. Because a drone records while traveling to a call, it may pass over and film private backyards and capture bystanders, faces, license plates or activities unrelated to the event that caused the drone to launch. The court nevertheless rejected the argument that every drone video was automatically exempt from disclosure merely because it came from the police drone program.
