Abstract

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.

手持式手枪的保留：比较两种技术的交叉 RCE

目的本研究比较了两种不同的手持枪支保留战术（HRT）的有效性。方法在强制培训期间，30 名巴西新招募的警察进行了手持枪支保留战术模拟练习。在 30 秒内，对手试图解除新警察的武装。在每一轮中，新兵的表现被编码为成功或失败。新招募人员被随机分配到两组，在交叉设计中，这两组在各个阶段都使用了两种战术。在第一阶段，对手试图从警官手中拔枪。在第 2 阶段，对手也可以攻击或制服警官。结果记录了 1029 次试验，其中第 1 阶段 546 次，第 2 阶段 483 次。在第 1 阶段中，各种技巧的效果没有明显差异。仅考虑第二阶段，模型显示 T2 有显著差异。多层次回归模型评估了单个变量对成功概率的影响。结果表明，在攻击者试图击中警官并试图解除其武装的情况下，T2 似乎对警官更安全。该研究项目有助于在部门内制定以证据为基础的决策。

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.
