Flock Safety cameras across Yuba-Sutter county are logging vehicle movements 24/7. We’re documenting what the Sheriff’s Office isn’t telling the public — and what your Board of Supervisors needs to answer for.

What is this

Automated license plate readers — explained

Flock Safety cameras photograph every passing vehicle, log the license plate, time, and location, and feed that data into a searchable network. The Yuba County Sheriff’s Office operates this network — and shares it with other agencies — without meaningful public oversight.

📷

Always-on surveillance

Cameras run continuously, building a database of where every vehicle has been.

🔁

Shared without notice

YCSO shares data with outside agencies — with no public disclosure of who or why.

📋

No audit trail

More than half of database searches contain no documented reason — a likely state law violation.

Key findings

What the records show

57% blank reason rate. YCSO’s own audit data shows officers ran searches with no logged justification — a likely violation of Civil Code § 1798.90.52 (SB 34).

Policy contradicts contract. YCSO Policy 433 retains data for only 60 days — but peer agencies cite state law requiring one year minimum. No statutory basis given for the shorter period.

December 2025 platform change. Flock removed officer-level logging from its portal, eliminating an entire accountability layer — placing all California agencies in likely non-compliance with state law.

No sharing agreements on record. Despite appearing as a confirmed sharing partner on other agencies’ transparency portals, YCSO has no interagency data-sharing agreements on file.
