Available in PDF, EPUB and Kindle. Book excerpt: The delayed response of law enforcement to calls for service has become a hot button issue when evaluating police department performance. While it is often assumed that faster response times could play an important role in quelling potentially violent incidents, to date there is no empirical evidence to support this claim. In this paper, we measure the effect of police response time on the likelihood that an incident results in an injury. To overcome the endogeneity between more severe calls being issued a higher priority, which requires a faster response, we take several steps. First, we focus on a subset of calls for service categorized as "Major Disturbance - Violence" that all receive the same priority level. Second, we instrument for police response time with the number of vehicles within a 2.5 mile radius of the call at the time it is received at the call center. When controlling for beat fixed effects, this instrumenting strategy allows us to take advantage of the geographical constraints faced by a dispatcher when assigning officers to an incident. In contrast to the OLS estimates, our two-stage least squares analysis establishes a strong, positive causal relationship between response time and the likelihood that an incident results in an injury. The effect is concentrated among female callers, suggesting that faster response time could potentially play an important role in reducing injuries related to domestic violence.

Available in PDF, EPUB and Kindle. Book excerpt: The procedures and results of a response time analysis study, which was designed to assess the value of police response to a variety of incidents, are summarized. The two primary objectives of this Kansas City, Missouri, study were: (1) analysis of the relationship of response time to the outcomes of on-scene criminal apprehension, witness availability, citizen satisfaction, and the frequency of citizen injuries in connection with crime and noncrime incidents; and (2) the identification of problems and patterns in reporting crime and requesting police assistance. The study design/data collection process continued over a 3-year period. Data were collected by civilian observers, communication tape analysis, and telephone and personal interviewers. Observers accompanied officers in the field to collect data on travel times and on-scene activities, while tape analysts collected dispatch times by timing verbal exchanges recorded on communications unit tape recordings. Victims of crimes and citizens who reported crime and noncrime incidents were interviewed to obtain reporting time data and to identify the problems encountered and patterns followed by those citizens reporting incidents or requesting police services. To analyze the relationships between response time and outcomes, three intervals in response times were considered: citizen reporting, communications dispatching, and police travel time. Variations in these intervals were then analyzed to see how they affected the probability of making an on-scene arrest and contacting a witness on scene, and how they affected recovery from injuries sustained during the commission of crimes. In addition, to see if the length of response time affected citizen satisfaction, police dispatch and travel times were again analyzed, along with other factors (such as citizens' social characteristics, expected response times, and perceptions of how long response took) considered to be possible determinants of citizens' satisfaction. Results indicated that reporting time was longer than either the time taken to dispatch a call or the time taken to travel to a call, and was nearly as long as the combined time taken to dispatch and travel to a call. For a large proportion of the crimes discovered some time after the incident had occurred, response time was found to be unrelated to the probability of making an arrest or locating a witness. For those crimes involving a victim or witness, reporting time was the strongest time determinant of arrest and witness availability. Citizen satisfaction was more closely related to citizens' expectations and perceptions about response time than to actual response time.

Available in PDF, EPUB and Kindle. Book excerpt: V. 1. The relationship between police response time, outcomes of calls for police assistance, and citizen crime reporting is analyzed in a study performed in Kansas City, Missouri. This study was conceived and developed to test the assumption that responding quickly to calls for police service will produce the most desirable outcomes, and to identify those problems and patterns which might affect how quickly a citizen reports a need for police service. The design of the study and data collection spanned 3 years, although the primary data were collected during 1975, in Kansas City. Trained civilian observers accompanied officers into the field to collect data on travel times and on-scene activities, while tape analysts collected dispatch time data by timing telephone and radio exchanges recorded by the communications unit. Interviewers questioned victims of crimes and citizens who reported crime and noncrime incidents or requested police service. The calls for service making up the data base came primarily from a target area selected for its high rates of robberies and aggravated assaults. The data covered the entire spectrum of police service, including both Part I and Part II crime calls, potential and noncrime calls, and traffic accidents. An introduction to the project is provided, and the setting of the subject area and the search are described. The examination of the sample design and the data collection process is illustrated by tables. -- v. 2. The analysis and findings of a Kansas City, Missouri. Study of the relationship between police response time, outcomes of calls for police assistance, and citizens, crime reporting are presented. This research was initiated to evaluate assumptions regarding rapid police response as an effective operational strategy and to identify problems and patterns which account for citizen delays in reporting crimes to the police. To test these assumptions, response time was conceptualized as consisting of three intervals: citizen reporting, communication dispatching, and police travel time. Variations in these intervals were then analyzed to see how they affected the probability of making an on-scene arrest, contacting a witness on-scene, and how they affected recovery from injuries sustained during the commission of Part I crimes. Additionally, the problems citizens encounter when reporting crimes and the patterns or actions citizens follow prior to reporting were identified and analyzed for their effects on reporting delays. Relationships between citizens' social characteristics and both reporting time and problems and patterns were analyzed. To see if the length of response time affected citizen satisfaction, police response times were again analyzed, with other factors considered to be possible determinants of citizen satisfaction. These factors included citizens' social characteristics, how long citizens expected response to be, citizens' perceptions of how long the response actually took, and how important citizens thought response time was to the outcomes of the incident they reported or in which they were involved. Statistical analysis is presented regarding response time, arrest, the effects of patrol procedures on response times and crime outcomes, witness availability, citizen injury, problems and patterns in reporting, the process of reporting, and citizen satisfaction; statistical summaries of each of these subject areas are provided in individual appendixes. Results indicate that reporting time was longer than either the time taken to dispatch a call or the time taken to travel to a call, and nearly as long as the combined time taken to dispatch and travel to a call. Response time was found to be unrelated to the probability of making an arrest or locating a witness for the large proportion of Part I crimes that were discovered after the crime had occurred. For those crimes involving a victim or witness, reporting time was the strongest time determinant of arrest and witness availability. Travel time generally had a limited effect on these outcomes, though for some types of crime the influence was strong. Citizen satisfaction was more closely related to citizens' expectations and perceptions about response time than actual response time. Problems citizens encounter and patterns they follow in reporting crime were identified and were found to produce delay in contacting police. Voluntary actions by citizens explained more delay in reporting than did problems experienced by citizens in contacting the police.

This book was released on 2018-03-23 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proactive policing, as a strategic approach used by police agencies to prevent crime, is a relatively new phenomenon in the United States. It developed from a crisis in confidence in policing that began to emerge in the 1960s because of social unrest, rising crime rates, and growing skepticism regarding the effectiveness of standard approaches to policing. In response, beginning in the 1980s and 1990s, innovative police practices and policies that took a more proactive approach began to develop. This report uses the term "proactive policing" to refer to all policing strategies that have as one of their goals the prevention or reduction of crime and disorder and that are not reactive in terms of focusing primarily on uncovering ongoing crime or on investigating or responding to crimes once they have occurred. Proactive policing is distinguished from the everyday decisions of police officers to be proactive in specific situations and instead refers to a strategic decision by police agencies to use proactive police responses in a programmatic way to reduce crime. Today, proactive policing strategies are used widely in the United States. They are not isolated programs used by a select group of agencies but rather a set of ideas that have spread across the landscape of policing. Proactive Policing reviews the evidence and discusses the data and methodological gaps on: (1) the effects of different forms of proactive policing on crime; (2) whether they are applied in a discriminatory manner; (3) whether they are being used in a legal fashion; and (4) community reaction. This report offers a comprehensive evaluation of proactive policing that includes not only its crime prevention impacts but also its broader implications for justice and U.S. communities.
Book Synopsis Patrol Response to Contemporary Problems by : John A. Kolman
Download or read book Patrol Response to Contemporary Problems written by John A. Kolman and published by Charles C Thomas Publisher. This book was released on 2006 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook instructs patrol officers in their roles and responsibilities as first responders, with attention to new and evolving threats and responses to incidents that have broadened the scope of responsibility of the patrol officer. The first of the five parts of the book contains four chapters on patrol officer's preparation and conditioning. These chapters focus on the importance and features of mental and physical fitness and preparing for various police encounters, some of which may involve a fight for survival. The four chapters of Part 2 address training and equipment. The chapters discuss the principles of combat shooting, the specifications of intermediate rifles for use in patrol work, specialty impact systems that can be used as less-lethal force options, and first responders' recognition of explosives. Part 3 consists of three chapters on various types of patrol procedures: the use of police dogs in patrol operations, vehicle stops, and building searches. The four chapters of Part 4 consider patrol responses to critical incidents. One chapter instructs patrol officers in the responsibilities of first responders at the scene of a hostage/barricade/suicide incident. A second chapter describes the tactic of "immediate action/rapid deployment," which is recommended for patrol officers who are the first responders to a violent attack in progress that involves multiple actual and potential victims. A third chapter describes the planning and implementation of procedures for a unified command when multiple agencies are responding to a mass disaster. A fourth chapter focuses on knowledge and procedures used by first responders in their handling of disasters caused by terrorists' weapons of mass destruction. The three chapters of Part 5 instruct patrol officers in preparing for civil litigation that alleges violations of constitutional rights due to officer actions.
