In-hand handgun retention: A crossover RCE comparing two techniques
Purpose
This study compared the effectiveness of two different in-hand handgun retention tactics (HRTs). HRTs are used when a suspect grabs the officer's weapon to avoid shooting.
Methods
During mandatory training, 30 Brazilian police recruits engaged in a HRT simulated exercise. For 30 s, an opponent tried to disarm the recruit. In each round, recruits' performances were coded as success or failure. Recruits were randomly assigned to two groups that used both tactics across sessions in a crossover design. During Phase 1, the opponent tried to pull the gun from the officer. In Phase 2, the opponent could also strike or submit the officer.
Results
1029 trials were recorded, 546 for Phase 1 and 483 for Phase 2. No significant difference between techniques' effectiveness was found in Phase 1. Considering only Phase 2, the model revealed a significant difference in favor of T2. Multilevel regression models assessed the influence of individual variables on the probability of success.
Conclusions
The results suggest that T2 seems safer for the officers in scenarios where the attacker tries to hit the officer while attempting to disarm them. This research project has contributed to developing evidence-based decision-making within the department.
期刊介绍：
The Journal of Criminal Justice is an international journal intended to fill the present need for the dissemination of new information, ideas and methods, to both practitioners and academicians in the criminal justice area. The Journal is concerned with all aspects of the criminal justice system in terms of their relationships to each other. Although materials are presented relating to crime and the individual elements of the criminal justice system, the emphasis of the Journal is to tie together the functioning of these elements and to illustrate the effects of their interactions. Articles that reflect the application of new disciplines or analytical methodologies to the problems of criminal justice are of special interest.
Since the purpose of the Journal is to provide a forum for the dissemination of new ideas, new information, and the application of new methods to the problems and functions of the criminal justice system, the Journal emphasizes innovation and creative thought of the highest quality.
