Prop 47’s impact on crime in California

by · Oct 24, 2024 2:37 pm

When California voters passed Proposition 47 in 2014, the goal was noble: decrease incarceration rates for nonviolent offenders and redirect resources towards rehabilitation and public safety programs. The measure reclassified certain felonies to misdemeanors, thereby lowering the severity of penalties for certain offenses, and has been touted as a revolutionary step in California’s criminal justice reform. Proponents argued that this would lead to reduced recidivism and better community outcomes. However, a decade later, the reality is far from the success story many hoped for. A recent paper by the Manhattan Institute discusses some of the ways in which Prop. 47 has negatively impacted public safety and health and put strain on county resources.

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.

Recidivism trends in California: New CDCR report

by · Feb 21, 2024 2:55 pm

Recidivism rates are down, according to a new report by the California Department of Corrections and Rehabilitation (CDCR). In a press release accompanying the report, they state that “the report marks the second year of data showing the effects of the passage of Proposition 57, and the findings point to lower recidivism rates for those who earned credits from participation and completion of rehabilitative programming.”  But this statement is misleading. While the data showed a slight decrease in recidivism rates, correlation does not equal causation, and this would be an overly simplistic interpretation of the data. There are other factors that could have contributed to recidivism rates, such as the COVID-19 pandemic, which influenced crime rates and caused many court closures and temporary suspensions of intakes and transfers to CDCR, which likely influenced recidivism measures in this report. The report did not rigorously evaluate the impacts of Prop 57, and therefore, the findings are not sufficient to demonstrate a casual relationship between Prop 57 and reduced recidivism rates.

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 . . .

California violent crime up 6.2% in last year: 2022 data released

by · Jul 14, 2023 8:50 am

In a recent release, California Attorney General Rob Bonta released 2022 crime statistics for the state, revealing a 6.2% increase in the violent crime rate compared to 2021. The report, “Crime in California 2022,” also noted a 6.2% increase in the property crime rate. In this post, I discuss the findings from this report and display the data points graphically.

The problem with reducing reliance on incarceration: A commentary on Vera’s “new paradigm” on sentencing

by · Feb 16, 2023 2:06 pm

The United States should move away from incarceration and ultimately work toward a system that creates “real safety,” according to a new, widely circulated report from the Vera Institute of Justice. In the report, the authors claim that severe sentences do not deter crime nor help survivors of crime heal, and therefore are not achieving their intended purpose. However, the argument seems to be rooted in emotion rather than facts. The research actually presents a more nuanced picture.

The controversy regarding incarceration is not new, and has remained a major topic of debate in recent years. Clearly, there are many different opinions regarding the utility of incarceration and its effectiveness, many of which are emotionally-driven and not rooted in facts. Rather, the research on incarceration presents a very nuanced picture. It is simply naive to think that any one policy would be 100% effective or 0% effective, and these types of “all-or-nothing” arguments are often rooted in emotion rather than facts.

In this post, I’ll give an overview of the lengthy report’s executive summary and give my thoughts regarding their key points. Stay tuned for part two of this post, where I will perform a deeper assessment of the report in its entirety.

Comparing nationwide violent crime estimates: Summary-based vs. incident-based reporting

by · Nov 22, 2022 10:53 am

The FBI released official 2021 crime statistics last month, but the data leaves major gaps in our understanding of national-level crime rates. Unfortunately, the numbers are incomplete this year because 36% of U.S. law enforcement agencies, some of them major cities, failed to submit their crime reports. This is largely because the FBI made major changes to the way that it collects crime data, making the submission process much more complicated. Rather than following the arduous process, many agencies simply declined to participate in last year’s data collection. In comparison, 2020 crime statistics included data from 85% of U.S. law enforcement agencies.

This post briefly reviews agency participation rates and discusses what that means for our current understanding of national-level crime. Then, using data from the years 2017-2020 (all of the years for which data from both systems are available),  I examine whether the two systems produce similar violent crime estimates.

Violent crime is a key issue for U.S. midterm election

by · Nov 7, 2022 11:47 am

Crime has become a big issue in the U.S. midterm elections. According to a recent Gallup poll, crime ranked as the second most important issue among voters, with 71% of registered voters saying it was either “extremely” or “very” important to their vote. This came second after the economy, which 85% of voters said would be extremely or very important to their vote. According to a different Gallup survey released a few weeks ago, more than half of Americans (56%) said there was more crime in their area compared to a year ago. According to Gallup, “That’s up a whopping 11 points from 2021 and 18 points from 2020, and is the highest mark ever measured.” This issue was a concern across party lines, with 73% of Republicans, 51% of Independents, and 42% of Democrats all agreeing that crime is getting worse (in 2020, these percentages were 38%, 38%, and 37%, respectively).

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.
