Decoding Prop 47: What recent audit findings reveal about the impact in San Bernardino and Riverside counties

by · Aug 23, 2024 2:29 pm

If you’ve been following California’s criminal justice reforms, you’re likely familiar with Proposition 47. Passed in 2014, Prop. 47 reclassified certain nonviolent offenses from felonies to misdemeanors, with the main goal of alleviating pressures on the state’s prison system by decreasing incarceration rates for nonviolent crimes. Reclassified offenses include drug possession, forgery, as well as instances of burglary, theft, and shoplifting wherein the stolen property amounts to less than $950.

Proponents believe that reducing incarceration rates for nonviolent offenses can lead to better rehabilitation outcomes and more efficient use of public resources, while critics argue that it has caused an increase in theft and drug-related crimes as well as an increase in reoffending. A recent audit by the Joint Legislative Audit Committee delves into how this measure has played out in San Bernardino and Riverside counties. In this post, I’ll break down the key takeaways from this extensive audit.

The power of communities in crime prevention: Insights from Baltimore

by · Apr 12, 2024 11:08 am

Crime tends to be concentrated in specific areas within cities, with about 50% of crime occurring on just 5% of streets. One police strategy that can help combat this is known as “hot-spot policing,” which has been shown to reduce violent crime in multiple studies.  Another factor that can help reduce crime in an area is when citizens exercise “informal social control.” Informal social control refers to the ability of community members to regulate behavior and maintain order through cohesive relationships, mutual trust, and willingness to intervene.  It involves residents taking actions to prevent and address crime and disorder in their neighborhoods.

One common assumption is that the chatoic and disordered nature of high-crime hot spots renders residents incapable of playing a significant role in crime prevention. However, a new study conducted in Baltimore seems to reveal otherwise.

Unveiling the impact of depolicing on crime: Insights from Denver’s neighborhoods

by · Mar 1, 2024 3:45 pm

A new research study published in Criminology examined the impact of sudden and sustained reductions in proactive policing (i.e., “de-policing”) on violent crime across neighborhoods in Denver, Colorado, leveraging the onset of the COVID-19 pandemic and social unrest after the murder of George Floyd as exogenous shocks. The study utilized multilevel models to analyze the impact of large-scale reductions in police stops and drug-related arrests on violent and property crime in the city.

Analyzing homicide trends: Republican vs. Democratic leadership

by · Oct 19, 2023 1:22 pm

In the ever-evolving landscape of American politics and society, the question of how political affiliation relates to social phenomena remains a topic of enduring interest. One such subject, the fluctuating rates of homicide, serves as a poignant case in point. Numerous researchers, thinktanks, and policymakers have examined the stark variations in homicide rates that have emerged across these political divides. However, with so many factors at play influencing homicide rates, it becomes increasingly difficult to know how much variation is attributable to differences in political affiliation. In this post, I will dissect views from thinktanks on both side of the aisle and attempt to make some sense of this controversy. Continue reading . . .

Vallejo, CA officially declares state of emergency over police shortage

by · Aug 1, 2023 12:10 pm

Last week, the city of Vallejo, California officially declared a state of emergency due to its lack of police officers, Daniel Egitto of the Vallejo Times-Herald reports. Over the last several months, the Vallejo Police Department (VPD)’s officer shortage has been worsening, with five officers leaving since March, and another three scheduled to leave within the next month.

PA state police data shows no racial profiling in traffic stops: Study

by · May 25, 2023 12:35 pm

The question of racial bias in police traffic stops is a highly debated issue. Some analyses have shown that certain racial or ethnic groups are disproportionately represented in traffic stops, leading many people to allege racial profiling and discrimination. However, it is not accurate or fair to claim that all police traffic stops are inherently racist. Other factors can contribute to racial disparities in police stops, including differences in driving behavior, geographic location, and crime rates in specific areas. As more research is conducted on this topic, it becomes more apparent how much context and other factors can play a role in traffic stop decisions. For example,  research that adequately accounts for the impact of contextual and situational factors has found that racial disparities may not be as pronounced as previously thought, and that they are often explained by other factors unrelated to race.

This was the case in a recent study examining traffic stops in Pennsylvania, which found no evidence of racial profiling. According to the full-length report, the Pennsylvania State Police (PSP) stopped more than 440,000 drivers in 2022, 78.5% of whom white. In comparison, 14.4% were Black, and 8.2% were Hispanic. To conduct the study, the PSP partnered with Dr. Robin Engel and the National Police Foundation to ensure that the evaluation was independent and external to the department. Overall, these data should inspire public confidence in the police. It also suggests that PSP’s approach could serve as a promising model for other agencies.

Unsound statistical analysis misrepresents racial profiling in California police stop data

by · Jan 30, 2023 1:53 pm

Findings from the California’s Racial & Identity Profiling Advisory (RIPA) Board’s Annual Report released earlier this month have sparked controversy after the results revealed that nonwhites are dispropotionately represented in police stops. The report also claimed that, of those stopped, nonwhites were searched more frequently, arrested more frequently, and more frequently engaged in physical confrontations with police officers. This led many people to conclude that the police are in fact, racist. However, it’s important to note that the practice of policing is far more complicated than what can be captured in datasets. While these data appear straightforward, studying racial bias is complicated.

There are myriad contextual factors at play that affect officer decisionmaking and police-citizen interactions, such that it is nearly impossible to attribute racial disparities solely to any one cause. Unfortunately, contextual factors are often not easily measured, or they might be ignored on the basis that these details are “less important.” But ignoring these key details leaves us with an incomplete understanding of the dynamics influencing these police encounters. So when it comes to the RIPA Board’s report, the findings seem straightforward, but a closer look shows some holes in the methodology that likely undermine the validity of the findings. To this end, the Peace Officers Research Association of California (PORAC) conducted a critical analysis of the report that highlighted numerous problems with the RIPA data and the methodology used in the report. In this post, I will summarize the key issues raised by the PORAC.

Misconceptions about racial disparities in police investigations: Results from Tucson

by · Nov 4, 2022 11:13 am

Debates about racial inequalities in the criminal justice system have ramped up in the last several years. This has been largely driven by discussions about racially-biased police violence, but many also speculate about disparities in how the police treat crime victims. For example, one common belief is that the thoroughness of police investigations varies based on victim and officer race. But a recent study published in The Journal of Law and Economics (subscription required for access) suggests otherwise, at least in the context of residential burglary.

2021 national crime rates are a mystery as FBI transitions to a new data system

by · Oct 21, 2022 7:29 am

Earlier this month, the FBI released the national-level crime statistics for 2021. According to that data, violent crime, particularly murder, remained a major issue in the United States. Crime remained relatively consistent from 2020 to 2021 with no statistically significant changes between years, though violent crime was still elevated compared to 2019 levels. From 2020 to 2021, national levels of violent crime decreased slightly (-1.0%), largely driven by decreases in robbery (-8.9%). Murders, however, increased (+4.3%). The data is available for download via the Crime Data Explorer, or it can be accessed using a new tool called the Law Enforcement Agency Reported Crime Analysis Tool (LEARCAT). But the data this year may be lower quality than years past, limiting our ability to draw inferences about national-level crime rates.

Policymakers and researchers rely on these data to understand state and national crime trends, but that may be more challenging this year. Unfortunately, the FBI’s plan to modernize its reporting of crime data has not gone according to plan, so it’s hard know how accurate these 2021 estimates are. The new system has advantages over the old system, but it is much more cumbersome and time-consuming to use, which has negatively impacted law enforcement agencies’ willingness to submit their data. And because of these low participation rates, there are huge gaps in nationwide crime statistics for 2021.
