Redactions and withholdings

The agency cited legal grounds in its response to request item 10. These are recorded as agency-cited justifications; the archive is not stating that the agency’s interpretation has been independently validated.

Full withholding

Network Audit and Organizational Audit

The agency stated that both audits were investigatory records and cited Government Code § 7923.600(a). In the same paragraph, it also cited Civil Code § 1798.90.55(b) and Government Code § 7927.705.

Open question: The response does not describe the fields, date range, or segregable portions of either audit.

Partial redaction

Administrative Event Log

The agency stated that the raw Event Log contained investigatory-record information and that it removed information it considered not subject to disclosure before producing the spreadsheet.

Open question: The response does not identify which rows, fields, values, or identities were removed or match each redaction to a specific authority.

Important questions remaining

What access existed before the 2025 contract?

Training and patrol-access emails date to 2023, while the supplied county contract was approved and executed in 2025. The current bundle does not contain the agreement or arrangement supporting the 2023 access.

Which retention rule controls?

The written response and Flock contract describe a 30-day default. Policy 473 says data downloaded to the server should be stored for a minimum of one year. The records do not reconcile those statements.

Where is the permitted-agency list?

Agency statement

The response refers to records listing California agencies permitted to access Amador data, but the archive does not yet publish a verified agency-by-agency list.
