Neighborhood climates of legal cynicism and complaints about abuse of police power†

Research findings show that legal cynicism—a cultural frame in which skepticism about laws, the legal system, and police is expressed—is important in understanding neighborhood variation in engagement with the police, particularly in racially isolated African American communities. We argue that legal cynicism is also useful for understanding neighborhood variation in complaints about police misconduct. Using data on complaints filed in Chicago between 2012 and 2014, we show that grievances disproportionately came from racially segregated neighborhoods and that a measure of legal cynicism from the mid-1990s predicts complaints about abuse of police power two decades later. The association between legal cynicism and complaints is net of prior complaints, reported crime, imprisonment, and other structural factors that contribute to the frequency and nature of interactions involving police and residents. Legal cynicism also mediates the influence of racially isolated neighborhoods on complaints. The mid-1990s is the approximate midpoint of a half-century of police scandals in Chicago. Our research findings suggest that contemporary complaints about police misconduct in highly segregated Chicago neighborhoods are grounded in collectively shared historical memories of police malfeasance. They also suggest that persistent complaints about police misconduct may represent officially memorialized expressions of enduring racial protest against police abuse of power.     

Aqueous Fluid as a Viable Substitute for Vitreous Fluid in Postmortem Chemistry Analysis

Vitreous fluid sampling for postmortem chemistry analysis is discouraged in pediatric forensic cases involving head trauma due to the risk of introducing retinal artifacts. Aqueous fluid is physically separated from the posterior chamber of the eye, and therefore, unlikely to produce vitreal artifact when sampled. Analysis of aqueous fluid is therefore proposed as a substitute for vitreous. Vitreous and aqueous fluid was sampled concurrently from 28 pediatric and 55 adult decedents, and sodium (Na), potassium (K), chloride (Cl), urea nitrogen (UN), creatinine (Cr), and glucose (Glc) concentrations were compared. Significant correlation existed between all analytes regardless of age or postmortem interval, and linear regression equations were derived. Aqueous concentrations were generally higher than vitreous for Na, K, and Cr and were marginally lower for Cl, UN, and Glc. Assuming vitreous fluid as a standard for correlating postmortem chemistry to antemortem serum values, aqueous may be a viable substitute for vitreous when expected differences are considered.     

A Mixture Model for the Number of Gunshot Residues Found on Suspects' Hands

Quantifying the strength of gunshot residue (GSR) evidence requires scientific knowledge about the number of particles expected to be found on individuals who were or were not involved in a shooting. However, controlled experiments demand expensive resources in terms of microscope time and labor, which restricts the data of most studies to only a small group of individuals. We suggest a novel method that exploits data collected routinely on suspects during the daily work of forensic laboratories. These observational data relate to both persons who were involved in a shooting and innocent individuals. We suggest a mixture approach with different models for the number of gunshot residue particles in each group and develop an iterative algorithm to estimate the probabilities of observing the evidence under the defense proposition that the suspect is innocent and under the prosecution assumption that he is not. The method is applied to data of more than 500 suspects collected by the Israel National Police Division of Identification and Forensic Science. The analysis shows that the probability of finding three or more GSR particles on the hands of innocent suspects is very small, less than 1.5 in 1000 cases. Our new method enables researchers to use data on real cases, possibly supplemented by experimental data, in order to estimate the probabilities of a given GSR finding under the defense and prosecution propositions.

Auditing as a tool of government accountability? Exploring divergent causal mechanisms through three Honduran cases

Audits of government entities offer a potential tool to hold public officials to account and to improve the functioning of public administration; however, empirical studies of audit impacts show mixed results. This is largely due to the diversity of audit regimes with different goals and accountability mechanisms, which yield different causal chains. In this study, I compare three distinct audit regimes with distinct casual mechanisms in Honduras. I find that backward-looking audits, which aim to hold officials accountable for past behavior or performance, require effective horizontal accountability mechanisms to investigate and prosecute cases. Forward-looking audits, which aim to hold officials accountable for future behavior or performance, require independent accountability mechanisms, a systematic follow-up methodology, public dissemination, and pressure from the media and civil society. Complementary initiatives that build on audit recommended reforms are found to strengthen these weaknesses in the causal mechanism linking audits to outcomes.     

The impact of public sector accounting reform on corruption: Causal evidence from subnational Indonesia

It is widely believed that the adoption of quality public sector accounting practices can assist in reducing corruption. In theory, accounting reform, especially the shift from cash-to accrual-based methods, leads to the production of much improved financial information, which ultimately can be used by citizens to hold government more accountable and limit corruption. Empirical evidence from cross-country analyses appears to support the theoretical predictions. We investigate the impact of accounting practices on corruption among districts in Indonesia. We use external financial audits to measure the adoption of reforms and the number of corruption case court convictions as our proxy for corruption. We estimate Poisson regression models using instrumental variable techniques to identify the causal effects of adopting accrual-based accounting procedures on corruption. We show that the employment of improved accounting methods is strongly associated with declining corruption. However, after accommodating the endogeneity of accounting practices, we determine that reform adoption has no effect on corruption.
