The purpose of this paper is to evaluate officer and civilian race/ethnicity disparities during ten years of officer-involved shootings (OIS).

Internal affairs, personnel and geospatial data were triangulated for 253 OIS at the Dallas Police Department from 2005 to 2015. Multinomial regression models were used to evaluate the relationship between civilian and officer race/ethnicity in OIS, controlling for officer, situational and neighborhood factors.

In total, 48 percent of unique OIS involved a non-Hispanic black civilian and most OIS occurred in Hispanic majority neighborhoods (48 percent). Officer age and number of shooters on scene were the only variables significantly associated with officer race/ethnicity. Most notably, officer race/ethnicity was not associated with the race/ethnicity of the civilian during OIS incidents.

There is limited scientific evidence on whether officers of certain races/ethnicities are disproportionately likely to engage in OIS with civilians of a particular race/ethnicity due to the relative rarity of such events.

Law enforcement officers (LEOs) suffer from premature mortality, intentional and unintentional injury, suicide and are at an increased risk for several non-communicable disease outcomes including cardiovascular disease and several cancers, compared to those employed in other occupations. Repeated exposure to stressful and traumatic stimuli is a possible mechanism driving these adverse health outcomes among LEOs. To better identify the sources of these health problems, the purpose of this paper is to determine the feasibility of conducting a cohort study using physiological measures of stress (e.g. heart rate) with LEOs; perceptions of the FitBit device, including LEO buy-in and attitudes associated with the protocol.

Data were collected from ten recent graduates of the Dallas Police Training Academy.

Results suggest that officer buy-in and protocol compliance was high. Officers were eager to participate in this study, and completion of weekly surveys was 100 percent. Minute-level missing data from wearable devices was relatively low (25 percent), and 90 percent of participants wore the FitBit devices on more than 90 percent of study days.

Results from this study suggest that wearable physiological devices can be effectively used in law enforcement populations to measure stress.

The purpose of this paper is to examine the impact of school safety measures, including SROs and safety personnel, on school-related delinquency and perceived safety.

Specifically, a comprehensive search of the literature was performed to identify studies published between January 1, 1998 and July 1, 2016 that focussed on structural school safety measures such as metal detectors, cameras, closed circuit television systems, and access control measures and/or school resource officers in primary and secondary schools. Only studies that relied on randomized controlled trials and pre-test/post-test designs evaluating the impact of at least one school safety measure in reference to a control condition were eligible for inclusion.

The results of this exhaustive search revealed 32 unique study samples that met the inclusion criteria. Results from the studies suggest that implementation of more security measures may not be an effective policy. More safety measures often result in a decline of student-perceived safety. Study limitations and directions for future research are also discussed.

Results from this meta-review can provide educational administrators, superintendents, and school safety policymakers with a synthesis of only the most rigorous and valid studies that evaluate the impact of school safety measures on both actual and perceived school-related delinquency and safety. This information will provide school safety decision makers with a state-of-the-art synthesis of how school safety measures impact school-related delinquency problems and safety, and which measures appear to be most effective for informing the allocation of scarce resources.
