Sources for every figure on this site

The build refuses to ship a page containing a statistic that is not in this table. Where a figure is a snapshot or an estimate, the caveat is printed with it rather than left off.

Key	Figure	Source
`rel_family`	34.2% — of victims under 18 in sexual assaults reported to law enforcement were assaulted by a family member	Snyder, Sexual Assault of Young Children as Reported to Law Enforcement, Bureau of Justice Statistics NCJ 182990 (2000)

`rel_stranger`	7.0% — were assaulted by a stranger	Snyder, BJS NCJ 182990 (2000) This is the share of cases REPORTED TO LAW ENFORCEMENT, which is not the same as the share of cases that occur.

`taylor`	2015 — California’s Supreme Court held Jessica’s Law’s blanket 2,000-foot residency restriction unconstitutional as applied to San Diego County parolees	In re Taylor, 60 Cal. 4th 1019 (2015)

Footage

Every full-bleed band on this site is a seven-second loop built from one of two kinds of source. Filmed footage is licensed from Pexels and the photographer is credited on the band itself as well as here. Generated footage is abstract by construction — it depicts no person, no place, no record and no interface, and it is labelled as generated wherever it appears.

On what the footage may show

No frame on this site shows an identifiable child. Every candidate clip was reviewed as a still before selection, and clips containing identifiable faces, brand marks, or readable third-party text were rejected rather than cropped. The generated clips were prompted with an explicit prohibition on people, faces, hands, children, text, logos and interfaces, and were reviewed on the same basis.

How this site was built

Static HTML, generated by a build script. No framework, no analytics, no third-party requests of any kind — enforced by a build gate, not by intention.
The instruments are plain JavaScript in /assets/engine.js. They compute in your browser, make no network calls and store nothing.
Loops encoded with ffmpeg; the wrap is a one-second cross-dissolve of the clip’s tail over its head, so the join is continuous.

Status of this document

This is a design document. No system described here has been built, procured, piloted or deployed, and nothing on this site should be read as describing an existing programme. It is published so the concept can be argued with before anyone spends money on it.
