Technological Innovation and Police Officers' Understanding and Use of Force

Today, the TASER is a ubiquitous less‐than‐lethal force technology lauded for its ability to curb police officers' use of excessive and lethal force. Although less injurious than other weapons, concerns exist that the TASER can still be misused by police officers. This article uses ethnographic observations and unstructured interviews across three urban police departments to describe how the TASER affects officers' understanding and use of force in beneficial and unintended ways. I find that officers understand and use the TASER as a device that can enhance safety for themselves and suspects, including in cases where the TASER is used in lieu of lethal force that officers believe would have been justified. Despite these benefits, understanding of the TASER as a safety‐enhancing technology also influences the use of excessive force via TASER by young, inexperienced officers, ultimately contributing to the very problem TASERs were intended to ameliorate.     

Do they Aggress Earlier? Investigating the Effects of Ego Depletion on Police Officers’ Use of Force Behavior

Endowed with the state monopoly on the legitimate use of even potentially lethal force, it is intolerable for police officers to act outside the governing legal and ethical framework. At the same time, officers are expected to exert self-control and refrain from excessive use of force when they deal with provocative and perilous situations. This study sought to investigate corresponding self-control and self-control failures through the role of ego depletion in the decision to use force by police officers. Two experiments were conducted using officers from a German State Police force, requiring the participants to use force against a provocative role player. Experiment 1 found that the ego depletion measure failed and there were no differences between the groups. Using a different ego depletion method, experiment 2 found that ego-depleted participants aggressed earlier than controls. These results indicate that circumstances that produce ego depletion could lead to the inappropriate use of force through reducing self-control. This has major implications for the police use of force and how we understand police officers’ decision-making in response to provocation.     

Police Use of Less Lethal Force: Does Administrative Policy Matter?

Scholars have long theorized that constraining police officer discretion via organizational policy improves decision-making. Empirically, prior research shows that more restrictive lethal force policies result in a reduction in the number of police shootings and in racial disparity. Yet, researchers have never examined the impact of less lethal force policies in relation to the full spectrum of less lethal force tactics. In addressing this research void, we examine 3,340 use of force incidents from three US agencies, each varying in terms of policy direction and restrictiveness. The results consistently show that officers working within the most restrictive policy framework used force less readily than officers who operated within more permissive policy environments. Hence, police administrators wishing to reduce coercion should consider the potential effect that a more restrictive policy may have on such behavior.     

Women Police

Abstract

This study investigated the use of force by and against women police officers using survey data from a large sample of female and male officers in six departments. Results suggested that female officers and same-gender female-female officer pairs used less force, and were less likely to use physical force, in police-citizen encounters when compared to their male counterparts. There was no evidence supporting the proposition that citizens used less force against female officers compared with male officers. In fact, the findings indicated that citizens used significantly more force against female officers relative to male officers in domestic calls. Although female officers were more likely to engage in underpredicted policing; that is, use less force than the situation would normally dictate, underpredicted policing was not related to an increase in the likelihood of officer injury. Implications for women officers, police use of force, and the institution of policing are discussed.     

The Effect of Police Use of Lethal Force on Murder Levels in American Cities Before and After Ferguson

We assess the effects of police use of lethal force on subsequent murders by victim race and armed status before and after the August 2014 death of Michael Brown in Ferguson, MO. We regress monthly murder levels on instances of police use of lethal force by race and armed status controlling for fixed effects, population, unemployment, and murders in the prior month using city-level data for 93 cities from 2013 to 2015. For 2013–2015, we find that a police lethal force incident predicts a 1.8% increase in murders 2 months following the incident. However, prior to Ferguson, a police lethal force incident increases murders by 4.5% (after 2 months) and we are unable to find any evidence of differential responses to police use of lethal force based on victim race. However, we find evidence of differential responses to police use of lethal force based on victim armed status. Post-Ferguson, police use of lethal force is associated with significant differential responses based on victim race. In addition, we see a shift in the aggregate-level response to police use of lethal force. Post-Ferguson, a police lethal force incident decreases the murder level by 3.8% 3 months following the incident. In addition, lethal force incident involving a non-black victim decreases the number of murders by 4.3% while an incident involving a black victim increases the number of murders by 2.1% (after a 2-month lag). Changes in policing following the events of Ferguson had a generally positive but uneven effect.     

Police Attitudes about the Use of Unnecessary Force: An Ecological Examination

An unexplored explanation for police opinion about their use of unnecessary force can be framed within the research examining police behavior in the context of its geographic location. Using Klinger’s (1997) theory of social ecology as a guide, a vignette research design was employed to survey officers in four departments of varying size and structure. It was hypothesized that officers assigned to higher crime areas would more likely accept the use of unnecessary force by another officer as well as be unlikely to believe that the use of unnecessary force would be reported to a supervisor. Bivariate results and multivariate analyses show support for both hypotheses. Implications for future research and theoretical development are discussed.     

Force,Stress, and Decision-Making Within the Belgian Police: the Impact of Stressful Situations on Police Decision-Making

Stress and fear are inevitable aspects of the police job and may have a large impact on police officers’ decision-making process. Many studies have explored how stress and fear may influence assessments of police officers, especially with regard to the use of force. This article aims to contribute to this research domain by reporting the findings from two empirical studies among Belgian police officers: a quantitative study of police officers’ attitudes towards and experiences with the use of force and a qualitative study on the influence of stress and emotions on officers’ decision-making and assessment abilities and accuracy of shooting. Both studies confirmed that stress and fear are often present in Belgian police practice. One of the main findings is that Belgian police officers are anxious about the consequences of their actions because they know they will be held accountable for them. The pressure that results from this accountability can make it even more difficult for police officers to react to stressful situations. Therefore, we need to look for the right balance in this difficult position, by providing tools that support police officers in making daily decisions, and help them do their job as effectively as possible.     

Uncertainty and the use of force among Venezuelan police officers

Literature often emphasizes the use of force as a distinctive feature of police work, while risky encounters and uncertainty are conditions under which such work is carried out daily. Conditions leading to the use of force by the police have been associated with the presence of menacing minorities, losing verbal control, the youth and lack of experience of officers, and critical physical proximity between officers and suspects. Additionally, defiance towards the police has often been linked to increased force used by the police. It is here proposed that uncertainty also fosters police officers’ dispositions to use force. In this study, four focus groups were conducted with officers from two Venezuelan municipal police departments in October 2003, presenting a hypothetical scenario progressing from contact with suspects towards an open confrontation involving a shooting. Officers perceived, through different phases of the scenario, an encounter of no easily predictable outcome with suspects, involving potential harm to the police and bystanders. A pattern seemed to appear among officers in which overcoming real or assumed resistance became the central issue. When physical confrontation with suspects became evident, self defence was the clearest justification for the use of force, though the use of force was also defended by officers without further elaboration on the requirements and conditions for effectively thwarting aggression. It appears that uncertainty about the outcome of a situation fosters both the disposition and the justification for using force.

The impact of TASERs on police use-of-force decisions: Findings from a randomized field-training experiment

This paper presents findings from a randomized field-training experiment designed to study the impact TASERs on police officers’ use-of-force decisions. Officers were randomly assigned to either a treatment group (with TASERs) or a control group (without TASERs) and then participated in training scenarios involving different levels of suspect resistance. The study investigates whether and to what extent officers armed with the TASER use it as an alternative to other types of less-lethal force (e.g., empty hands, pepper spray, and the baton) and the firearm, controlling for the level of suspect resistance. The findings indicate that officers who were armed with the TASER were significantly less likely to deploy pepper spray and the baton in response to aggressive physical resistance. Additionally, the results show that officers equipped with the TASER were less likely to discharge their firearm when confronted with suspect resistance that was potentially lethal. No differences in police behavior occurred in response to passive suspect resistance.     

Is there a distinct profile of police officers accused of violence? The Israeli case

In recent years, the Israeli National Police has come under attack for excessive use of physical force. This article focuses on the organizational characteristics of police officers suspected of committing offenses involving the illegal use of force. A random sample of 612 official files opened, investigated, and completed between 1993 and 1998 was examined. The findings show that there are no salient differences between the proportion of the suspect police officers serving at the different geographic police districts in the sample and their proportion in the total police force in recent years. Complaints tend to be submitted against police officers in operational and investigative functions, especially against those of middle and low ranks. Regarding the files' characteristics, many significant differences are found between files opened against regular police (RP) officers (who fulfill traditional police functions) and those opened against officers of the Border Police (BP, who fulfill mainly internal security-related tasks among the Arab population). These differences are mainly explained by factors related to organizational features of the BP.     

A comparative study of the attitudes of Urban,Suburban and Rural Police Officers in New Jersey regarding the use of force

This article examines the attitudes of sample populations of urban, suburban and rural police officers in New Jersey in regard to a hypothetical use of force scenario. The aim of the study is to identify similarities and differences in the perceptions of officers who are faced with the same type of hypothetical situations but who are exposed to different training, procedural and environmental factors. Police officers in the United States receive different types of training in each state that might influence their attitudes towards the use of force. A pilot study was conducted comparing two urban police departments from two different states and showed some differences in the attitudes of the surveyed officers. To further explore these differences, a more refined look at three police departments in one state (New Jersey) was conducted as part of a doctoral dissertation of the lead author. Research questions are aimed at identifying the differences in the frameworks for the justification of force based on a host of variables. The research questions stipulated that there will be some significant differences in attitudes towards the use of force by the officers, based on physical location of the communities they police. The findings of the study identified additional factors that might influence the officers’ attitudes. Twelve focus groups, four at each of the sites, were analyzed and it appears that there may be a geographic and demographic influence on how the officers respond to the scenario.     

Police use of TASERs in the restraint and transport of persons with a mental illness

The mentally ill are overrepresented in the statistics of individuals killed or injured by police and it is understandable that police would seek a weapon, such as a TASER, that is less lethal than a firearm. However, it appears that use of TASERs is not without risk, especially in certain groups, including the mentally ill. The risk of injury to vulnerable people with a mental illness from TASER weapons must be weighed against the risk that escalation to lethal force may cause if a person with an acute mental illness requires restraint. When police officers are carrying out their duties under mental health legislation it is recommended that TASERs be used only when an individual is imminently likely to sustain or to cause grievous bodily harm. This article recommends changes to the Western Australian Police TASER training programs and proposes mandatory medical assessments after the use of TASER restraint.     

Situational and officer-based determinants of police coercion

Using data collected as part of an observational study of the police in Indianapolis, Indiana, and St. Petersburg, Florida, this article examines police use of force to gain a better understanding of why the police resort to force. Like analyses from previous observational studies, the present inquiry borrows from both sociological and psychological theoretical orientations to explore various determinants of force. Unlike previous examinations, the universe of behaviors considered is substantially expanded to include numerous types or levels of force, ranging from verbal commands and threats to the use of impact methods. An ordered probit analysis of 3,116 police-suspect encounters shows that officers often respond to legal stimuli (e.g., suspects' resistance, safety concerns) when applying force. Countering previous findings, it found that officers were not more coercive toward disrespectful suspects. However, the analysis revealed that officers were also influenced by extra-legal factors. Male, nonwhite, poor, and younger suspects were all treated more forcefully, irrespective of their behavior. In addition, encounters involving inexperienced and less-educated officers resulted in increased levels of police force. The implications of these findings, for both policy and future research, are considered.     

Use of force by female police officers

Do female police officers use force at the same rate as male police officers? This research examined the use of force by officers in a large, suburban police department during a seven-year period (1993-1999). Use of force reports completed by departmental policy for each use-of-force incident (n = 1,863) and data on arrests (n = 31,778) were examined. A rate of force, defined as the number of use-of-force incidents per one hundred arrests, was computed for male and female officers for each type of force used. A suspect-injury rate, defined as the number of suspects injured per one hundred arrests, also was computed.Force was used in only a small percentage (5.9 percent) of the arrests made. Injury to the suspect (not including the effects of OC spray) occurred in an even smaller percentage (1.6 percent) of arrests, and injury to the suspect resulting in treatment at a hospital (generally, emergency room treatment) occurred in a still smaller percentage (0.7 percent) of arrests.No statistically significant difference between female and male officers was found in the overall rate of force or in the rate of unarmed physical force. Female officers had a lower rate of weapon use when all types of weapons were considered together (p. < 0.05), but not when the different types of weapons were considered individually. Female officers also had a lower rate of any suspect injury (p. < 0.05), but there was no statistically significant difference in the rate of suspect injury resulting in treatment at a hospital. The differences found, even when statistically significant, were small in absolute terms.     

The effects of supervisor education and training on police use of force

Police supervisors play a critical role in preventing unreasonable use of force. Despite their importance, only a few studies have examined the influences of supervisors on their subordinates’ daily practices, especially on their uses of police force. To bridge this gap, the current study explored the relationship between supervisors’ education level and use of force training and subordinate officers’ use of force practices. Using police use of force reports from 2004 to 2007 in a single urban police department, the current study examined how supervisor education and training impact on police use-of-force and found both highly educated and trained supervisors moderate their subordinate officers’ uses of higher levels of force.     

Can You Build a Better Cop?

Research Summary

By drawing from psychology and economics, we present an experimental evaluation of a procedural justice training program designed to “slow down” police officers’ thought processes during citizen encounters. We find that officers who were randomly assigned to participate in training were as engaged in the community as similarly situated officers, but they were less likely to resolve incidents with an arrest or to be involved in incidents where force was used. These changes were most evident among officers who worked in areas with a modest level of risk.

Policy Implications

Police officers who are actively engaged with the public can reduce crime through general deterrence and by arresting criminals. Nevertheless, excessive discretionary arrests and the use of force by officers can reduce public trust in the police. To date, there is scant evidence as to how police departments can successfully train officers to balance enforcement and public trust in the field. Through our study, we demonstrate that a relatively minor supervisory intervention may cause substantive changes in how police and citizens interact with each other.     

SWAT and non-SWAT police officers and the use of force

Although many police departments use Special Weapons and Tactics (SWAT) teams, surprisingly there is very little research on them. This study examined the use of force by SWAT and non-SWAT police officers. SWAT officers may be socialized to use force as a result of the dangerous situations they frequently encounter, and thus more likely to use force in non-SWAT situations. The results of this research note, however, indicated there was a statistical nonsignificant relationship between SWAT status and the use of force. Implications of the findings of this study are discussed.     

Characteristics associated with the prevalence and severity of force used by the police

Using a diversity of samples, sources of data, measures of force, analytical methods, and theoretical frameworks, prior research reported that the prevalence of police use of force ranges from 0.8% to 58.1% of police-suspect encounters. In addition, few characteristics of officers, suspects, police departments, or neighborhoods are associated consistently with the amount of force used by the police. Using self-report data by police from 7,512 adult custody arrests in six jurisdictions, this study found that the associations between encounter-level characteristics and police use of force are dependent on the incorporation of suspects' resistance and on the measure of force used.     

Women Police Officers and the Use of Coercion

Abstract

Despite numerous advances in the last thirty years, women police officers continue to face acceptance issues in a male-dominated occupation. Qualitative accounts of policewomen have noted that many of the integration barriers stem from traditional assumptions about police work, much of which revolves around the cultural mandate to display one's coercive authority over citizens. Female officers are often perceived as unwilling (or lacking in ability) to use coercion when encountering citizens. Unfortunately, little empirical evidence is available to support this claim, as gender studies that specifically examine the use of coercion have tended to focus on excessive force. Using data collected as part of a systematic social observation study in Indianapolis, Indiana, and St. Petersburg, Florida, this research examines both verbal and physical coercion that policewomen use in day-to-day encounters with citizens. The results of this study challenge one of the most fundamental stereotypes levied against women police officers. Contrary to traditional assumptions, female police officers (compared to their male counterparts) are not reluctant to use coercive force, and examinations of both verbal and physical force reveal few differences in not only the prevalence of each behavior, but also in the commonly associated explanatory factors. The article concludes with the implications of these
