Evaluation of Police Training on LGBTQ Issues: Knowledge,Interpersonal Apprehension,and Self-Efficacy

The present study evaluates outcomes of a five-hour training session to prepare law enforcement personnel (LEP) to work effectively with LGBTQ individuals and communities. The training was developed collaboratively with the local police department, an LGBTQ community organization, a group of diversity trainers, and the researchers. Approximately 120 LEP participated in the training, and 81 completed pre- and post-test assessments of knowledge, self-efficacy, and interpersonal comfort with LGBTQ people. Paired-sample t-tests demonstrated significant increases in knowledge and confidence in using LGBTQ-affirming tactics on the job. No significant differences were found in participants’ comfort in working with LGBTQ community members. Implications for LEP training on LGBTQ issues and research in assessing LEP for behavioral and affective change are discussed.     

Further Pseudo-Operational Trials with the Lumicyano Double- and Co-Fuming Process for the Detection of Latent Fingermarks

This study presents a number of pseudo-operational trials on plastic bags investigating the double- and co-fuming process of a one-step fluorescent cyanoacrylate (Lumicyano^TM) in comparisons with the two-step process with basic yellow 40 (BY40) staining for the detection of latent fingermarks. The results demonstrate that both Lumicyano solution and dye contribute to the increased detection of latent fingermarks during the double-fuming process (trial 1). Co-fuming the Lumicyano solution and dye separately (at a concentration of 8%) but simultaneously was less effective than 8% Lumicyano (trial 2). Co-fuming Lumicyano 8% and an additional 8% Lumicyano dye by weight was more effective than Lumicyano 8% (trial 3), possibly due to increased fluorescent material deposition during co-fuming allowing for better visualization. The use of BY40 after Lumicyano resulted in a considerable increase in detected fingermarks.

Volatile Organic Compound Profiling from Postmortem Microbes using Gas Chromatography–Mass Spectrometry

Volatile organic compounds (VOCs) are by-products of cadaveric decomposition and are responsible for the odor associated with decomposing remains. The direct link between VOC production and individual postmortem microbes has not been well characterized experimentally. The purpose of this study was to profile VOCs released from three postmortem bacterial isolates (Bacillus subtilis, Ignatzschineria indica, I. ureiclastica) using solid-phase microextraction arrow (SPME Arrow) and gas chromatography–mass spectrometry (GC-MS). Species were inoculated in headspace vials on Standard Nutrient Agar and monitored over 5 days at 24°C. Each species exhibited a different VOC profile that included common decomposition VOCs. VOCs exhibited upward or downward temporal trends over time. Ignatzschineria indica produced a large amount of dimethyldisulfide. Other compounds of interest included alcohols, aldehydes, aromatics, and ketones. This provides foundational data to link decomposition odor with specific postmortem microbes to improve understanding of underlying mechanisms for decomposition VOC production.     

“That shit doesn't fly”: Subcultural constraints on prison radicalization

Many observers describe prison subcultures as inherently and irredeemably antisocial. Research directly ties prison subcultures to violence, gang membership, and poor reintegration. In extreme cases, research has also suggested that prison subcultures contribute to incarcerated people joining radical groups or embracing violent extremist beliefs. These claims, however, ignore key differences in the larger cultural and social context of prisons. We examine the relationship between prison subcultures and prison radicalization based on semistructured qualitative interviews with 148 incarcerated men and 131 correctional officers from four western Canadian prisons. We outline several imported features of the prison subculture that make incarcerated people resilient to radicalized and extremist messaging. These features include 1) national cultural imaginaries; 2) the racial profile of a prison, including racial sorting or a lack thereof; and 3) how radicalization allowed incarcerated men and correctional officers to act outside the otherwise agreed-to subcultural rules. Our research findings stress the importance of contemplating broader sociocultural influences when trying to understand the relationship between radicalization and prison dynamics and politics.     

Does police patrol in large areas prevent crime? Revisiting the Kansas City Preventive Patrol Experiment

Research Summary

The Kansas City Preventive Patrol Experiment (KCPPE) was seen by its developers to have produced “consistent evidence of the lack of effects of any consequence on crime,” a conclusion that was to have a strong impact on assumptions about police patrol for almost half a century. We identified the original official crime data from the KCPPE, and reanalyzed outcomes focusing on a comparison of the “proactive” versus “control” beats (“reactive beats” were criticized because of violations of treatment integrity); examining broad categories of crime (to increase statistical power); and using count regression models. Our findings are not unequivocal, but point to modest impacts of police patrol on crime in police beats.

Policy Implications

Our findings suggest that lessons drawn for half a century from the KCPPE need to be revisited. The KCPPE does not show that police patrol in large areas has no influence on crime, and this finding is consistent with several more recent studies. At the same time, we note that the effects of patrol in the KCPPE using our analysis strategy, and those found in other studies of preventive patrol in larger areas, are about half that found in hot spots policing studies. This suggests that police agencies ideally should invest in focused hot spots policing initiatives. However, absent an ability to manage such initiatives, or the crime analysis capabilities to identify crime hot spots routinely, simpler preventive patrol schemes to utilize uncommitted patrol time can be seen as potentially effective in preventing crime.
