Abstract

fetched live from OpenAlex

Les caméras corporelles sont souvent évaluées comme un outil pouvant amener les policiers et les citoyens à agir plus conformément aux attentes et normes sociales lorsqu’ils sont filmés. La Ville de Montréal a récemment mené un déploiement partiel de caméras corporelles afin d’évaluer la faisabilité et la pertinence d’équiper l’ensemble de ses policiers de cette technologie. Le présent article vise à évaluer l’impact quantitatif de l’implantation de caméras corporelles sur plusieurs indicateurs liés à la qualité des interventions police-citoyens à Montréal. Ces indicateurs proviennent de statistiques officielles, de sondages auprès de personnes ayant reçu un constat d’intervention et de données de la cour municipale de Montréal. Ces données ont été analysées en utilisant la méthode des doubles différences, c’est-à-dire en comparant les périodes avant et pendant l’implantation des caméras corporelles, pour le groupe expérimental et le groupe contrôle. Les résultats proposent que les caméras aient eu peu d’impact sur les interactions police-citoyens, principalement en raison du nombre de cas très limité ou d’un niveau de satisfaction à la base élevé qui rendaient improbable la détection d’un quelconque effet statistiquement significatif.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
