Limitations and reproducibility

Fully reproducible from the retained FBI API response with Windows PowerShell 5.1 or newer and no additional packages.: The public release includes the immutable source response, transformation and validation script, generated tables, release manifest with SHA-256 digests, source audit, quality report, and build instructions. Running scripts/build.ps1 without -Refresh rebuilds from the retained response; -Refresh intentionally acquires potentially revised source values and therefore requires a new release.

  • The principal series is a statewide aggregate and cannot identify which agencies or counties drove a change.
  • Reported offenses are not necessarily unique stolen vehicles, victims, suspects, arrests, recoveries, or pursuits.
  • The release contains no vehicle make or model and cannot directly measure the Kia and Hyundai theft wave.
  • The release does not measure attempted theft, failures to yield, or incidents in which officers did not initiate a pursuit.
  • The release does not contain police staffing, deployment, prosecution, detention, or task-force activity.
  • FBI source values can be revised after this immutable release.
  • Washington population coverage declines to approximately 95.7%–96.1% in the second half of 2025.
  • The United States series is a descriptive benchmark, not a causal counterfactual for Washington.
  • All three pursuit-law changes occurred during a month; the descriptive period table excludes those transition months.
  • FBI offense totals do not reconcile with separately published WACIC and WATPA stolen-vehicle figures; the measures must not be treated as interchangeable.
  • Policy-period averages are unadjusted, highly confounded descriptions and must not be described as causal effects.
