Non-preservation is documented in the sheriff's office's own records responses, including that nothing was sent to any agency (KRK-E045). Those responses never affirm footage of Robinson existed, which is exactly what can no longer be checked.

Provisionally supportedconfidence: high · Gemini 3.1 Pro (Google) — independent check run via gemini-3.1-pro-preview · run 2026-08-26-check-gemini · unreviewed draft
The sheriff's office confirmed in a written response that responsive surrender-area surveillance footage is no longer available due to standard 30-day auto-deletion policies. The claim is provisional only because the official response does not explicitly confirm that the suspect was captured on the purged footage, only that responsive records were destroyed.
Provisionally supportedconfidence: moderate · GPT-5.1 (OpenAI) — independent check run via gpt-5.1 · run 2026-08-26-check-gpt · unreviewed draft
Records responses from the Washington County Sheriff’s Office state that responsive surveillance footage was “no longer available after the 30-day retention period” and had not been sent to any other agency, which supports the claim that potentially relevant video was allowed to auto-delete. The main uncertainty is that the responses do not explicitly confirm that this deleted footage actually showed Robinson’s surrender, though separate accounts place the surrender at that facility; this keeps the claim at provisional rather than fully established.
Provisionally supportedconfidence: moderate · Grok 4.6 (xAI) — independent check run via grok-4.6 · run 2026-08-26-check-grok · unreviewed draft
Washington County Sheriff's Office records responses state that responsive surveillance footage is no longer available after the 30-day retention period and was never sent out to any agency. That non-preservation is documented in the office's own words. Strongest opposing consideration: the responses never explicitly confirm that footage of Robinson existed, and a 30-day auto-purge executing as designed is the null hypothesis for routine retention policy.
Provisionally supportedconfidence: moderate · Opus 5 (Anthropic) — independent check run via claude-opus-5 · run 2026-08-26-check-opus · unreviewed draft
The sheriff's office stated in its own written records responses that responsive surveillance footage is no longer available after the 30-day retention period and, to its understanding, was never sent to any agency — documentary, first-party, and adverse to the office's interest. What keeps this provisional is the gap the claim's wording papers over: the responses never confirm that footage depicting Robinson's surrender existed, only that whatever was responsive was not retained. The strongest opposing consideration is that a 30-day auto-purge executing as designed is the null hypothesis for essentially every sheriff's office, and no record shows a preservation request was made and ignored.
