What the videos couldn't include

The confession the jury couldn't weigh

The unsigned statement was used only to challenge Garrett's credibility. The Texas appeals court noted that jurors were told they could not treat it as evidence of guilt.

Sister Tadea Benz File 1014

A small fire, a real danger

The fire burned a small patch of floor, about 0.09 square meters. None of the ten passengers named in the arson counts suffered burns or had their clothing catch fire, but the court found they had been in real danger.

Kyota Hattori File 1013

Dramatic on screen. Careful on the page.

The episodes use illustrated recreations and squeeze real timelines into a couple of minutes. The case files work the other way. They lay the whole timeline out, cite where each fact comes from, and mark every key moment from the video as documented, reconstructed, compressed or dramatized.
