For a general presentation of the misnamed Automated License Plate Readers (ALPRs) and Flock Safety in particular, see deflock.me, Eyes On Flock, Have I Been Flocked?.
The terminology used in these pages.
Looking at ALPR logs of a few agencies:
In reponse to request 25-731, the city of Salinas refused to provide data.
As of November 21, 2025, the Palo Alto Police Department has not responded to a request sent on August 27, 2025.
The request 25-491 to the city of Redwood City was closed without any document being made public.
In response to request 25-2173, the city of Mountain View declined to provide “records related to queries made by outside agencies using our data”.
In response to request C000486-022226, the Riverside County Sheriff’s office provided the organization audit, but did not provide the network audit, invoking that “the public interest served by not disclosing the record clearly outweighs the public interest served by disclosure of the record”. The Sheriff-Coroner, Chad Bianco, toots on his 2026 California gubernatorial campain website “integrity” and “personal responsibility”.
