Abstract

OBJECTIVE

To examine the impact of a novel firearm 'pointing' policy that requires officers to document when they directly point their guns at citizens.

METHODS

Sixteen years (2003-2018) of narrative officer-involved shooting (OIS) reports from the Dallas Police Department were qualitatively coded to explore both the total frequency and specific characteristics of OIS before and after the policy change in 2013.

RESULTS

χ tests found that the firearm pointing policy was associated with a reduction in the proportion of 'threat perception failure' shootings (ie, those where an officer mistakes an item for a gun). Auto Regressive Integrated Moving Average analysis found that the policy change was associated with a gradual, permanent reduction in total OIS; however, that impact was not immediate.

CONCLUSIONS

Firearm pointing policies have the potential to alter organisational behaviour, particularly in highly discretionary shootings. It is unclear whether the specific mechanisms for the changes include more accountability through constrained discretion, reduced options to handle situations once officers' guns are drawn and pointed, or an effect on officers' timing and vision during ambiguous scenarios.

POLICY IMPLICATIONS

Although organisational change may be a long and complex process, reductions in OIS can prevent serious injuries and death. The policy change did not lead to an increase in the proportion of officers injured during OIS incidents.

摘要

目的

研究一项新的枪支“指向”政策的影响,该政策要求警察记录他们直接将枪指向公民的情况。

方法

对达拉斯警察局16年(2003 - 2018年)涉及警察的枪击事件(OIS)叙述性报告进行定性编码,以探讨2013年政策变更前后OIS的总频率和具体特征。

结果

χ检验发现,枪支指向政策与“威胁感知失误”枪击事件(即警察将物品误认为枪支的事件)比例的降低有关。自回归积分移动平均分析发现,政策变更与OIS总数的逐渐、永久性减少有关;然而,这种影响并非立竿见影。

结论

枪支指向政策有可能改变组织行为,尤其是在高度自由裁量的枪击事件中。尚不清楚变化的具体机制是否包括通过受限的自由裁量权提高问责制、警察拔枪并指向后处理情况的选择减少,或者在模糊场景中对警察的时机把握和视野产生影响。

政策启示

尽管组织变革可能是一个漫长而复杂的过程,但OIS数量的减少可以预防严重伤害和死亡。政策变更并未导致OIS事件中受伤警察比例的增加。
