Intelligence-led policing (ILP) was introduced in the 1990s as a proactive approach to policing, but to date, there is a lack of studies that have synthesized and summarized the central characteristics and insights of (quasi-)experimental studies related to ILP. This study aims to address this gap by synthesizing and characterizing the central…

Warrantless arrest laws for domestic violence (DV) are generally classified as discretionary, preferred, or mandatory, based on the level of power accorded to police in deciding whether to arrest. However, there is a lack of consensus in the literature regarding how each state's law should be categorized. Using three classification schemes, this…

This study reports the results of the process evaluation component of the Process and Outcome Evaluation of the Gang Resistance Education and Training (G.R.E.A.T.) program. The process evaluation consisted of multiple methods to assess program fidelity: (a) observations of G.R.E.A.T. Officer Trainings (G.O.T); (b) surveys and interviews of…

Background: A small but growing body of research evidence suggests that place-based police interventions generate significant crime control gains. While place-based policing strategies have been adopted by a majority of U.S. police departments, very few agencies make a priori commitments to rigorous evaluations. Objective: Recent methodological…

A study of the impact of community policing on calls for service, crime, and narcotics cases in four Houston (Texas) neighborhoods used time series analysis and examined lagged and dynamic effects. The analysis indicated that the community policing programs had no significant impact on neighborhood crime. (SLD)

Using a two-year time series, the impact on law enforcement pursuit behavior of two changes in pursuit policy in a police department was studied using the ARIMA computer program and Tobit analysis. Each policy change produced significant reductions in pursuits engaged in by police officers. (SLD)

Studied the experiences of 178 juveniles targeted by the Truant Recovery Program, a collaborative and nonpunitive school-law enforcement effort in California. Findings suggest that intensive cooperation between school and police may be effective in identifying troubled youth. Findings also raise questions about appropriate school and justice…

Used interrupted time-series analysis (ARIMA) to study the impact of legislation and judicial intervention on the use of deadly force by police officers in Philadelphia, Pennsylvania. Findings generally suggest that dynamic changes in the internal working environment can outweigh the influence of external mechanisms on deadly force use. Findings…

Examined the use of cellular digital packet data (CDPD) systems by a state police agency to support a problem-oriented policing project (POP), focusing on 20 officers. The CDPD data system should have improved the agency's POP operations, but in practice, the benefits were not clear. Few differences were seen between officers who did and did not…

Firearms play an important role in lethal domestic violence incidents. The authors review state laws regarding two policies to separate batterers from firearms: laws authorizing police to remove firearms when responding to a domestic violence complaint ("police gun removal laws") and laws authorizing courts to order guns removed from batterers…

An analytical technique is reviewed that allows a researcher to decompose informant reports into their respective trait, informant bias, and measure specificity using LISREL. The technique is illustrated in a study of decision making in 151 police agencies. (SLD)

Assessed the impact of the Mobile Digital Terminal technology (computers used to communicate with remote crime databases) on motor vehicle theft clearance (arresting a perpetrator) and recovery rates in Fort Worth (Texas), using a time series analysis. Impact has been ambiguous, with little evidence of improved clearance or recovery. (SLD)

Using data covering 111 weeks, the impact of 3 increasingly restrictive policies on reporting hot pursuits by police officers on the ratio of accidents to reported pursuits was studied. More restrictive pursuit policies did not increase noncompliance with reporting requirements. (SLD)

This article reports on a survey of administrators, counselors, and teachers from middle schools involved in the National Evaluation of the Gang Resistance Education and Training (G.R.E.A.T.) program. This survey was part of a multisite evaluation that also elicited the responses of students, parents, and officers teaching the G.R.E.A.T. program.…
