Interview with Prof. Richard Gill On Lucy Letby Case And More

Professor Richard Gill, emeritus professor of mathematical statistics at Leiden University and the statistician instrumental in overturning the wrongful conviction of Dutch nurse Lucia de Berk, explains the statistical flaws in the Letby prosecution and expresses cautious optimism about the Criminal Cases Review Commission process. He describes the shift rota chart as a textbook example of the Texas Sharpshooter fallacy — cherry-picking data after the fact to produce a compelling but spurious pattern. Gill is deeply concerned about the immunoassay insulin evidence, endorsing the work of Gwen Mork and Anna Milan as illustrative of how a cheap screening test was misused forensically. He draws an explicit comparison with the Ben Geen case and argues that British courts are systematically unprepared to evaluate contested forensic science. Gill calls for an independent medical investigation independent of the police, noting that investigators were operating above their competence level throughout.
