County audit finds documentation gaps in ALPR searches; community groups press for suspension or stronger safeguards
Summary
An independent audit found gaps in deputies’ documentation of reasons for automated license‑plate‑reader (ALPR) searches but found no evidence of improper sharing; the auditor noted that vendor Flock had terminated access. Community speakers called for stronger limits, warrants for searches, and a permanent end to ALPR use.
An independent audit of Sheriff’s Office use of automated license‑plate‑reader (ALPR) systems, presented to the Santa Clara County Board of Supervisors on June 22, identified weaknesses in how deputies documented reasons for data searches but did not find evidence of improper data sharing by Sheriff’s Office personnel.
Julie Ruhlin, the audit presenter, said the report focused on deputies’ use of ALPR data accessed through regional camera systems and the Northern California regional intelligence center. Audit reviewers found “room for improvement” in deputies’ documentation of search reasons and case‑linkage practices, and noted that many search records lacked a valid case number or an explicit written justification. Ruhlin said the audit did not uncover evidence that the Sheriff’s Office had shared ALPR data externally in violation of county policy.
Community members expressed alarm. Tim McKenzie and other speakers said the Sheriff’s Office was still accessing Flock Safety data as an end user despite a February board policy banning the vendor’s use as a county ALPR vendor; they argued this undercut the board’s authority and demanded warrants or stricter rules for ALPR searches. Other public commenters—including civil‑rights and community organizations—urged the board to permanently end ALPR use or, at minimum, adopt stricter oversight and require judicial warrants before searches.
The auditor said that during the audit period Flock Safety terminated access to its ALPR camera systems and that the Sheriff’s Office was not operating or accessing that data at the time of the presentation, though staff were working to reestablish some access. The board took the report and discussed ongoing monitoring; a motion to receive the item passed by roll call.
Why it matters: Residents and civil‑liberty groups warned that ALPR systems can enable mass surveillance and be used to track movements of immigrant communities and other groups; the auditor’s documentation concerns point to accountability gaps that the board or the Sheriff’s Office must address if ALPR data access is to continue under policy constraints.
Speakers: audit author Julie Ruhlin; Sheriff’s Office representatives (present but not quoted in detail in the transcript); multiple community advocates and researchers who urged banning ALPRs or judicial‑warrant requirements.
