A dark desk: one document tray holding a stack of redacted pages tagged in red, an empty tray beside it, an open ledger, a magnifying glass and a flatbed scanner.

The Ledger

Preserve the record. Track the changes.

Mirroring Canadian police disciplinary records — and watching when they disappear.

The Ledger captures every public disciplinary record, tribunal decision, and oversight-body report from Canadian police agencies — then detects when those records are removed, altered, or silently edited out of their official sources.

The method, in six objects

  1. A flatbed scanner, lid raised, lighting a page of redacted text.The captureEvery source URL is rendered in a headless browser, hashed with SHA-256 and stored, with its sub-resources written to WARC.
  2. A black document tray holding a stack of pages with a red tag.The preserved copyCapture is append-only. A re-fetch produces a new row; the copy already kept is never changed.
  3. An empty black document tray with the dust outline of a stack that is no longer there.The missing sourceWhen a record stops answering at its official address, the detector logs the first day it was gone.
  4. Two translucent pages overlaid; a red tag marks the one line that differs.Silent editsA record that changed without notice is compared against the copy on file, and the difference is logged.
  5. Two copies of the same page side by side, joined by a red line at one paragraph.ProvenanceEvery published row carries a source_capture_id that leads back to the archived original.
  6. A bound page on a reading stand under a desk lamp.PublicationNames become tokens, dates round to the quarter, small cells are suppressed, and the rest is released daily under CC-BY 4.0.

Special Investigations Unit (Ontario)The evidence collected by the SIU, including interviews with the affected person and police eyewitnesses, and video footage that largely captured the incident, gives rise to the following scenario. As was their legal right, the subject officer did not agree to an interview with the SIU or the release of their notes. In the afternoon of early 2026, the affected person was in custody at a police detachment. Earlier that day, they had been arrested in relation to an incident at a municipal building. While being processed for release following a period in detention, the affected person objected to a condition that would prohibit their presence at a location. The officer explained that an amendment could be made but indicated that the affected person would have to be returned to cells for a period. The affected person refused to accompany the officer to cells and a struggle followed in which they were forced to the floor. The affected person was eventually handcuffed and returned to a cell. Later that day, paramedics transported the affected person to hospital where they were diagnosed with injuries.pursuit_custody_injuryno_grounds2026-Q1
