Schneps and Colmez publish 'Math on Trial'
Prof. Leila Schneps and Coralie Colmez publish 'Math on Trial: How Numbers Get Used and Abused in the Courtroom'. The canonical popular reference on mathematical fallacies in criminal trials. Catalogues ten cases including Sally Clark and Lucia de Berk. The framework the book codifies — multiplication fallacy, selection-effect fallacy, prosecutor's fallacy, ecological fallacy — applies directly to the Letby shift-rota chart.
