Abstract
Abstract Purpose The introduction of community policing led to a significant increase in the number of police stations, particularly in urban settings. Police stations are largely assumed to have an impact on crime but there are few studies dedicated to the issue. Methods The concept of deterrence suggests a negative relationship between police and crime: an increased police presence should lead to a reduction of crime. While it is difficult to directly test that relationship, the present study takes advantage of two recent events in Montreal (Canada) to test the hypothesis that the closure of a police station causes an increase of crime in the surrounding area. Andresen’s Spatial point pattern tests and Wheeler and Ratcliffe’ weight displacement difference tests were conducted. Findings While tests suggest that crime geographic patterns were dissimilar pre- and post-closure, none of those differences support the deterrence hypothesis because the number of areas in which an increase in crime was recorded is lower than would be expected by chance. Similarly, decreases in breaking and entering, mischief, theft in or on vehicles and total crime were found, which does not support the deterrence hypothesis. Conclusions The study of hotspot policing led to the belief that police presence needs to be concentrated in both time and space if it is to have a significant preventive impact on crime. It also led to the development of strategies of concentrated policing that encompass a variety of prevention actions aimed at specific individuals, specific crime types, and/or specific areas. Police stations provide something different: a concentrated presence at one point location with the ability to deploy to respond to any crime, at any time, in a particular area.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
