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.

The advocacy problem

Cherry-picked inputs make cherry-picked policy.

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

Liberty Evidence bar

  • State the research question plainly
  • Show every control — and every omission
  • Sensitivity and robustness, not one pretty p-value
  • Downloadable tables where claims are public
  • No “engine live” theater before the data is real

Approach

Evidence first. Interface second.

The product is not a chatbot skin. It’s reproducible analysis on a real site.

Public door This site — mission, honesty, and navigation. No stock “AI product” chrome.
Evidence pages FastAPI + clean HTML — tables, charts, methods, downloads. Same craft as Guns of Liberty.
Data plane Real extracts → clean files → published pages before big claims.

Honest inventory

What is live

Domain, TLS, this site, and the /evidence section. First pages may use public reference series while full multi-control panels are built.

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.
