The Post's fatal-shooting rates (6.1 vs 2.4 per million per year, 2015-2024), MPV's 2024 likelihood ratio (2.9x), and the Lancet/GBD age-standardized reconstruction (0.69 vs 0.20 per 100,000, 1980-2019, with all four group rates carried). Where a row carries both rates the published ratio re-derives live. Carried strictly as a measurement finding with no causal position; the essay names the benchmark debate and leaves it open. The release grows from nine tables to ten."

        "summary": "Verified-claims layer (v0.3.0). Added three sourced blocks that complete the series' strongest argument. FEDERAL_VALIDATION: the government's own statisticians already validated the open-source method, the BJS-sponsored assessment found the old Arrest-Related Deaths program captured at best 49 percent of law-enforcement homicides (collection suspended 2014), and the redesigned media-based pilot then identified 1,348 potential arrest-related deaths in ten months and estimated about 1,900 for the year. STRATIFIED_UNDERCOUNT: the Lancet/GBD misclassification broken out by group (highest for Black Americans at 59.4 percent, with every group's figures re-deriving and reconciling to the study totals). INTERNATIONAL: the Prison Policy Initiative cross-country rates per 10 million (US 33.5, more than three times the next-highest peer), carried with the explicit caveat that every country counts under a different definition, which is the series' own point. The release grows from six tables to nine."

        "date": "2026-07-22",
        "summary": "Record-level layer (v0.2.0). Added the overlap analysis, computed from Mapping Police Violence's own linkage columns (each MPV record carries a WaPo ID and, through 2021, a Fatal Encounters ID), so the three-list overlap needs no fuzzy matching. The finding: by 2015-2021 the civilian trackers converged, agreeing on more than 99 percent of cases, and the residual gap is definitional (about 50 non-shooting killings a year the Post's rule omits). A two-source capture-recapture on these lists is invalid (nested, non-independent, shown by a degenerate confidence interval); the valid undercount estimate comes from the GBD study, which found US vital statistics missed 55.5 percent of police-violence deaths."

Replaced the sparse, partly secondary-sourced annual figures with a complete matrix aggregated directly from each project's primary dataset: WaPo fatal shootings 2015-2024 (all 10,430 records) and MPV all-killings 2013-2024 (15,437 records). This corrected several figures (2019 fatal shootings is 993, not the 1,004 previously carried). Reframed the definition gap as the decade-long WaPo-vs-MPV difference (MPV builds on WaPo and adds non-shooting killings). Split the FBI series into distinct officer-coverage and agency-participation tables. Added a methodology and limitations doc."
