Advocacy pattern (E³-style)
- Narrow law sets, broad claims
- Weak or missing ownership / enforcement controls
- Little policing, poverty, or urban structure
- Defensive gun use treated as inconvenient
- Correlation sold as mandate

The truth engine gun policy deserves.
Liberty Evidence Engine is a transparent counterweight to advocacy-only stats tools — starting with the pattern behind Everytown’s E³: convenient laws, thin controls, confident conclusions. We aim for full confounders, published methods, and results you can verify.

Crime pockets: how concentrated is U.S. homicide in major cities?
National murder totals hide geography. Using 2023 major-city homicide counts against the FBI national murder estimate, see how much of the total sits in the top 5 / 10 / 15 / 25 cities — and what happens if you drop the largest city. Interactive cuts on real counts; not a causal gun-law model.
Are firearms the leading cause of death for children? What CDC numbers actually show
Both things can be true: on broad pediatric bands (especially 0–19 / 14–19), firearms lead recent CDC WONDER injury rankings — and for younger children the ranking collapses. The slogan’s truth depends on ages, comparison causes, and intent. Here are the numbers.
U.S. violent crime rate, 1985–2023
National violent crime rate per 100,000 residents — a public reference series for context. Not a causal claim about any single gun law.
The advocacy problem
Cherry-picked inputs make cherry-picked policy.

Honest inventory
What is live
Domain, TLS, this site, and the /evidence section — including a real-data urban homicide concentration page with browser-side cuts (top N / exclude largest). Still not a national causal engine.
What is not live yet
Full county panels, complete CDC/FBI/NCVS pipelines, and multi-spec robustness suites. Those land as additional /evidence pages — not a slider demo.
Next iron
Richer real datasets, documented regressions, downloadable parquet. Gunwriters get citable pages.
