Police interrogation

Abstract

We describe a study of more than 1000 interrogations by Metropolitan Police Officers. Obtaining a confession is found to be the paramount reason for interviewing a suspect. However, few suspects who did not initially confess changed their minds during the interview. 42% of suspects admitted their guilt—about the same number as obtained before tape recording of interviews was introduced. Strength of evidence and legal advice were the principal factors associated with confessing. The confession rate also varied according to which police station hosted the “interview”. An “accusatorial” style of questioning was associated with the possession of strong evidence against the suspect.     

Perceptions of children during a police interrogation: Guilt,confessions, and interview fairness

Abstract

Jurors are often provided with confession evidence and must determine whether the confession was true, false, coerced, or voluntary. As more juveniles are tried in adult criminal court, jurors must increasingly make these determinations about minors’ statements. In this study, mock jurors read an actual interrogation of a child suspect that included confession evidence, and then provided judgments regarding the coerciveness of the interrogation, the child's and police's knowledge and behaviors, and guilt. Child age (11 versus 14 years) and gender were manipulated and examined in relation to participant gender and pre-existing sympathy levels for juvenile offenders. Factors external to the suspect – participant gender and sympathy for juvenile offenders – interacted with child suspect factors to influence perceptions of the child, the interrogation, and guilt. When multiple factors were considered, perceptions of suspect credibility and police fairness were the strongest predictors of guilt and perceived culpability. The findings have implications for decision-making in cases involving juvenile defendants and confession evidence.     

Accusatorial and information-gathering interview and interrogation methods: a multi-country comparison

Suspect interviewing and interrogation practices have been studied in many different countries, including those in North America, Europe, Asia, and Australia. These studies have produced useful and interesting findings, while also leaving an opening for future inquiry. Specifically, previous research has noted that we might expect interrogation and interviewing practices to vary among different countries or regions, due to distinct approaches to suspect questioning. However, to our knowledge, few previous studies have examined the comparative use of tactics, techniques, and procedures employed to elicit confessions and information from criminal suspects across multiple countries. In the present study, using a consistent survey, we contrasted the interviewing and interrogation practices of 185 practitioners from America, Canada, and Europe, Australia, and New Zealand. In large part, we found that American and Canadian interrogators were similar to one another, and conformed to an accusatorial approach (in both deception detection and questioning techniques). In contrast, interviewers from Europe, Australia, and New Zealand conformed more to an information-gathering approach.     

Police Response to Crime

Abstract

Based on victim accounts provided by the National Crime Victimization Survey from 1992 to 1999, this paper examines issues related to police responses to reported incidents of assault, robbery, and rape. The primary goal was to determine the extent to which victim and offender race influence police responsiveness at various stages of the criminal justice system. The data indicate that overall, police exert more effort when victims are white. They arrive faster at the scene of the crime, and demonstrate more follow-up effort after the crime has taken place. However, they do not exert more, or less effort, during their initial visit to the crime scene, when there is proximate contact with the victims. This suggests that contextual factors may affect the penchant for discrimination. This relationship held even after controlling for other factors such as poverty, weapon use, injury to the victim, and location.     

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     

Police interviewing styles and confessions in Japan

Psychological studies of suspects' confessions have been conducted mostly in English-speaking and European countries, and the results may not generalise to countries whose cultures and policing practices differ. In particular, the difference between Japanese and Western laws may affect the roles that police interviewers play in suspects' confessions. This study examined the interviewing techniques used by Japanese police officers and associated features of the suspects' confessions. An extensive questionnaire was completed by 276 police officers across Japan. Detailed ratings of their interview techniques were factor analysed, yielding five factors: Presentation of Evidence, Confrontation, Rapport Building, Active Listening, and Discussion of the Crime. Based on these five factors, we identified four interviewing styles: Evidence-focused, Confrontational, Relationship-focused, and Undifferentiated. When interrogators employed the Relationship-focused interviewing style, suspects were more likely to make full confessions and to provide new information. By contrast, suspects were more likely to make partial confessions and were less cooperative when the police officers employed an Evidence-focused style.

The New York City Police Department,its Crime Control Strategies and Organizational Changes, 1970-2009

Over the last two decades, New York City has witnessed historic drops in crime. Numerous explanations for this crime decline have been discussed, and the New York City Police Department (NYPD) has been central to that debate, most notably because of the adoption of order maintenance policing and the implementation of Compstat. While those developments in the early 1990s are clearly important for understanding the potential role of the NYPD in the crime decline, those changes did not occur in a vacuum. This paper adopts an historical framework that places the role of the NYPD in the crime decline in the larger context of the department’s history, culture, and key events over a nearly 40-year span. This perspective suggests that many of the crime control strategies implemented by the NYPD over that time have been driven by internal and external crises, and that these strategies have also produced unintended consequences. With the historical analysis as a backdrop, the paper considers the ongoing debate over stop, question and frisk practices, and their disproportionate impact on minority residents, as the next potential crisis for the NYPD. The paper concludes with a discussion of the historical framework as a foundation for initiating a comparative dialog across law enforcement agencies regarding crime control strategies, their impact, and their consequences.

Police Officers on Drug Corners in Philadelphia,Drug Crime,and Violent Crime: Intended,Diffusion, and Displacement Impacts

On May 1, 2002, the Philadelphia Police Department launched Operation Safe Streets, stationing officers at 214 of the highest drug activity locations in the city 24 hours a day, 7 days a week. Interrupted time series (AutoRegressive Integrated Moving Average) models on weekly data isolated citywide and local program impacts on all violent crimes, murder, and reported drug crimes. Results showed no significant impacts on citywide weekly counts for drug crimes, homicides, or all violent crimes. Geographically focused analyses showed significant localized intervention impacts for both violent and drug crimes. Analyses of high‐drug‐activity non‐intervention sites suggest: the program impacts seen were not an artifact of history or local history; significant spatial diffusion of preventive benefits for violent crime; and probably significant spatial displacement for drug crime. Stationary targeted drug‐enforcement interventions like Operation Safe Streets may differentially affect the locational selection processes behind violent crime versus drug crime.     

Perceptions of coercion in interrogation: comparing expert and lay opinions

ABSTRACT

When confessions are entered into evidence in criminal courts, issues of coercion and voluntariness are important and often contested matters. Occasionally, defense attorneys proffer expert witnesses to testify about the coercive pressures of an interrogation and the risk of a false confession. Such testimony is often ruled inadmissible on the grounds that it does not inform the jury beyond its common knowledge. In our effort to test this judicial assumption about common knowledge, we surveyed jury-eligible laypeople (n?=?67) and social scientists specializing in interrogation and confessions (n?=?54) regarding their opinions about the coerciveness of prohibited interrogation tactics, maximization techniques, minimization techniques, and suspect risk factors and compared their ratings with a set of independent t tests. Laypeople gave lower ratings to the coerciveness of all sets of items representing interrogation techniques, and lower ratings to the vulnerabilities associated with suspect risk factors, as compared to social science experts. The disparities between laypeople’s and experts’ perceptions of coercion in interrogations demonstrate that such issues are not fully within the common knowledge of prospective jurors, and suggest the need to provide jurors with expert witness guidance when tasked with evaluating confession evidence.

Urgent issues and prospects in reforming interrogation practices in the United States and Canada

The current article presents a series of commentaries on urgent issues and prospects in reforming interrogation practices in Canada and the United States. Researchers and practitioners, who have devoted much of their careers to the field of police and intelligence interrogations, were asked to provide their insights on an area of interrogation research that they believe requires immediate attention. The submitted independent commentaries covered a variety of topics – from police recruitment, interrogation training, use of proper interrogation practices, and the treatment of confession evidence in court. Common concerns from the contributions pertained to the lag between scientific knowledge on interrogations and the application of such knowledge in the justice system, and the glaring disparity between the treatment of similar issues in the interrogation context versus other criminal justice contexts. A primary intent of this collection of commentaries is to serve as a resource pointing researchers in the direction of the fundamental areas that require immediate consideration and encouraging them to simultaneously pursue solutions to the overarching concerns that emerged from this project.     

Police recruits and perceptions of trust in diverse groups

Trust is critical in ensuring public co-operation with police and in turn building police legitimacy. Trust has been regarded as especially critical when police have sought to develop more positive interactions with diverse groups. Understanding how police officers perceive others and how this shapes trust in members of diverse groups is still developing. This study contributes valuable information regarding police perceptions of trust in minority group members; an area under-researched in policing studies, particularly in an Australian context. To understand how police recruit perceptions of socialization, interaction, and living and work choices affects their perceptions of trust in diverse groups of people, data were collected from a population of Police Recruits and Protective Service Officers (N = 1609) during pre-service awareness training. These were used in a Stepwise OLS model to ascertain opinions of trust in people distinguished by diverse identities. The results show socializing, and experiencing positive interaction whilst socializing with people from diverse groups, and the age of the participants, has a significant impact on the perceptions of trust police recruits have in members of diverse groups. However, this may not be enough to uphold positive levels of trust over time.     

‘Inappropriate but not crime’? Policing racial hatred in Sweden

ABSTRACT

Racial bias afflicts police practices across the globe. Police discrimination against and mistreatment of racial and ethnic minorities is indeed difficult to underestimate. While much attention has been thus paid to racially biased policing, fewer studies examine the question from the reverse angle, namely how the police themselves combat racist offences. This article offers empirical insights into the policing of racial hatred in Sweden, a relevant yet relatively understudied case. Drawing on interviews with police officers and crime investigators, I discuss law enforcement perspectives, e.g. perceptions and reasoning in relation to the investigation of racist offences. Findings evince a rather narrow approach as regards the constructions of racist motive that involves a relatively restricted use of bias labelling in identifying hate incidents, especially when the boundaries of racial hostility are perceived as blurred. I argue that while such an approach may reflect a legitimate effort to demonstrate the existence of a motive behind an offence, it may also lead to an underestimation of more mundane forms of racism and their harms inflicted upon racialized individuals and communities. The results have implications for ‘recognition’ and ‘belonging’ as benchmarks of democratic policing, and ‘the promise of inclusion’ associated with combatting hate crimes.

侦查讯问话语的对抗性与信息势能的选择

基于Hovland的信息传递说服模型并结合语言学研究中与信息势能相关的理论,构建了侦查讯问话语信息势能流动模型来分析对抗性讯问活动中信息势能的流动趋势。研究发现:犯罪嫌疑人通过提高知名度、增加可信度、回避核心话题、提供超量信息、表明动机等言语策略极力增强信息的势能,说服警察接受其提供的信息;警察采用阐释性发问、搁置、质疑、打断、拒绝等言语策略削弱犯罪嫌疑人话语的信息势能,阻碍犯罪嫌疑人的假供、乱供和翻供以获得真实的信息,达到讯问目的。     

论英国警察讯问较的发展

英国警察最初与普通公民一样，基本上不具有对犯罪嫌疑人的讯问权。司法判例以及20世纪前期发展的法官规则认可了事实上存在的警察讯问权并确立了基本的适用规则。由普通法调整的状况持续到20世纪80年代，制定法在规范警察讯问程序的同时也在一定程度上对公民的沉默权予以限制。警察讯问权总体上不断扩张，在这个过程中，普通法和制定法都努力保持警察侦查权与公民权利之间的平衡。
