Flock Cameras Tied to San Francisco Crime Drop as Privacy Bills Advance

San Francisco residents saw vehicle thefts fall 59 percent and break-ins drop more than 82 percent from early 2022 through August 2026, according to SFPD data analyzed by NPR. The change followed the 2022 recall of District Attorney Chesa Boudin, the appointment and subsequent elections of Brooke Jenkins, increased patrols, bait-car operations, and the March 2024 rollout of Flock Safety automated license-plate readers after voters approved Proposition E. City officials credit the cameras with enabling rapid identification of suspect vehicles and repeat offenders, sometimes paired with drones to document crimes in progress without high-speed chases.

A University of South Carolina study of 216 agencies that adopted Flock systems found an associated 11 percent reduction in car thefts in the first year, using difference-in-differences methods that compared adopting and non-adopting jurisdictions while testing against unrelated crimes such as shoplifting. The same study has not yet been peer-reviewed and did not examine break-ins. San Francisco Police Department statements attribute the larger local declines to the cameras’ ability to map movements of organized crews, though the cameras’ placement leaves gaps in many residential blocks where break-ins occur.

Senators Bernie Sanders and Jeff Merkley, along with Representative Alexandria Ocasio-Cortez, introduced legislation on October 2, 2026, that would bar federal agencies from using Flock cameras or their data and would condition Justice Department grants on similar state and local restrictions. The bill responds to a Washington Post investigation documenting at least 50 cases of alleged misuse by officers, including stalking and domestic surveillance. Sanders described the technology as creating an ankle-monitor equivalent for every driver and warned of a surveillance state benefiting private vendors.

Flock has stated it supports clear legislation and has offered optional features to limit abuse. Research on earlier, less extensive license-plate-reader systems found limited crime-reduction effects, while studies of fixed CCTV cameras showed modest declines, particularly in parking areas. The ACLU has campaigned against the systems, citing both efficacy questions and constitutional concerns over warrantless tracking of lawful travel. San Francisco officials have instead proposed tighter local rules and criminal penalties for data misuse rather than removal.
