Intervention à Radio-Canada Toronto sur la proposition de Doug Ford de rendre publics les registres de délinquants sexuels. J’explique pourquoi ces mesures augmentent surtout la sécurité perçue et non la sécurité réelle de nos sociétés.

Thank you to Public Safety Canada for truly putting your money where your mouth is. Canada is fortunate to have a national government that actively supports PVE (prevention of violent extremism) and listens to the voices of practitioners and researchers.

Fresh off the press! Using machine learning, we investigated potential sources of misclassification in the LS/CMI. Findings suggest that integrating age and placing greater weight on specific items could improve prediction. Gender was not a source of misclassification.
