    Rebuilding a Police Department in Free Fall with Brian O'Hara

    Minneapolis recorded more shooting victims than it had sworn police officers in 2021. At that time, a huge chunk of the department had walked out the door just as gun violence had surged and the city council was publicly vowing to reorganize what remained. Someone still had to show up and run the thing. That someone was Chief Brian O’Hara. A career law enforcement officer who started as a beat cop in Newark in 2001, Brian rose to become that city’s public safety director before taking on what may have been the hardest job in American policing: rebuilding the Minneapolis Police Department from near-collapse while simultaneously trying to win back a traumatized community. Brian O’Hara was the 54th Chief of the Minneapolis Police Department, taking over in the wake of the murder of George Floyd. He previously served as Deputy Mayor and Public Safety Director in Newark, New Jersey, and is the founder of the O’Hara Leadership Group, LLC.

    How The Federal Data Landscape Is Changing With Denice Ross

    Every crime rate, every per capita statistic, every trend line in American public safety depends on something most people have never thought about: the data infrastructure underneath it. You only notice it when it starts to break down. Today’s guest, Denice Ross, has seen this breakdown firsthand and it has informed her career ever since. Denice has served as the Chief Data Scientist of the United States under the Biden Administration, built the Police Data Initiative – an open data effort for police departments to voluntarily publish data – under the Obama Administration, and now runs the Data Policy Institute at the Federation of American Scientists. In this conversation, we get into what data has actually changed under the current administration. We also talk about the Census as the denominator for everything, declining survey response rates, and how Denice got a group of police chiefs to open up their records over cupcakes at the White House. Denice Ross is the Director of the new Data Policy Institute at the Federation of American Scientists, and the former Chief Data Scientist of the United States. In the Obama Administration, she co-led the Police Data Initiative which catalyzed law enforcement agencies to be more accountable by opening data about things like police use of force and citizen complaints.  Denice worked in New Orleans (where we first met) for many years, before and after Katrina, first for a nonprofit data intermediary and then serving in the Landrieu administration, where she established the city's open data initiative.

    Stitching Together America’s Criminal Justice Data with Mike Mueller-Smith

    The criminal justice system is big, it is complicated, and it is expensive. But how do we know what parts of it, if any, are working?  Enter Mike Mueller-Smith. A decade ago, Mike started building the Criminal Justice Administrative Records System (CJARS) a data infrastructure project that links criminal justice records across 40 states to employment outcomes, health data, and more. It is the kind of tool that makes you wonder why it didn’t exist sooner. In this episode, we get into why criminal justice data is so fragmented, what it takes to stitch it together, and what researchers keep finding once they can actually see the full picture. We also talk about Mike’s Justice Outcome Explorer, one of my favorite criminal justice data sites out there – a public dashboard built to help average Joes make sense of complex and sensitive criminal justice data. Mike Mueller-Smith is the Co-Founder and Director of the Criminal Justice Administrative Records System (CJARS for short), a data infrastructure platform that is modernizing American research and statistical reporting capacity. He also is an Associate Professor of Economics at the University of Michigan and does research on the multi-faceted determinants of crime in the U.S. and the broad-ranging consequences of our criminal justice policy.

    Guns, Data, and the Law with Thomas Chittum

    Every time a gun is recovered at a crime scene in America, a quiet process begins. The gun is traced backward through manufacturers, wholesalers, and retailers to find out where it came from and how it got to the scene. Most people have no idea this system exists, let alone what it entails. Tom Chittum has spent 25 years inside it. He's a former associate deputy director of the ATF and has spent his career at the intersection of federal law enforcement, firearms law, and the technology used to connect guns to crimes. In this episode, we get into how the legal landscape around gun ownership is shifting in ways most people haven't followed. We talk about how firearms tracing actually works, why the data is so hard to get and even harder to interpret,  and what the future of the law surrounding firearms might look like.  Tom Chittum was a career federal agent and retired from ATF as Associate Deputy Director. After leaving government service, he was Senior Vice President of Forensic Services at SoundThinking, the maker of the gunshot detection system, ShotSpotter. He is an adjunct law professor at UNLV’s Boyd School of Law, where he teaches ‘Firearms Law and the Second Amendment.’ He also works as a private attorney, representing federal law enforcement officers and advising on matters of firearms and explosives law.

    Using Social Networks To Reduce Gun Violence With Andrew Papachristos

    My guest today is Andrew Papachristos, one of the smartest people (though he is a Bears fan) thinking through how to use data to reduce gun violence. Andy has spent his career trying to read networks more systematically. He’s a professor at Northwestern University who studies how social ties and relationships shape who becomes a victim and who doesn’t and how that knowledge can be put to use before the next shooting, not just after. In this episode, we get into what network science actually is, how cities are using it to reach people at the highest risk, and why the same principles hold whether you're looking at Boston, New Haven, Newark, or Chicago. We also talk about what it actually looks like when violence intervention workers use this research well and what the current historic crime decline might be obscuring. Andrew Papachristos is the John G. Searle Professor of Sociology at Northwestern University, where he directs the Institute for Policy Research and CORNERS—the Center for Neighborhood Engaged Research & Science. His (insert adjective :P ) research uses network science and multi-method approaches to understand gun violence, gun markets, street gangs, and policing. He is one of the country's leading experts on how network dynamics shape gun violence and public safety.

    Crime Is Falling. Can Public Perception Catch Up? with Insha Rahman

    My guest today is Insha Rahman, the president of the Vera Institute of Justice, the oldest and largest justice reform organization in the country. Insha has spent the past ten years building out everything from bail reform research to a 501c4 focused squarely on the politics of public safety and brings a fascinating perspective to the conversation around making perceptions of crime and safety more responsive to what the data says is actually happening. In this episode, we get into why the data behind reforms like bail reform rarely matches the political story told about them, what cities like Camden, NJ got right during their first homicide-free summer in fifty years, and why Insha thinks the gap between crime perception and crime reality might finally be starting to close. Insha Rahman is the president and director of the Vera Institute of Justice, the oldest and largest criminal justice reform organization in the country. Insha is also the president and director of Vera Action, an independent 501(c)(4) organization. Insha is the first woman, immigrant, and Muslim to lead both organizations. Insha previously served as Vera’s vice president for Advocacy and Partnerships and the director of Vera Action since 2020. Insha got her start in this work as a public defender in the Bronx.

    A Deep Dive into Why Crime is Falling with John Roman

    Crime is falling fast in America , and, as the many different opinions on the podcast can attest, almost nobody can agree on why. My guest today has spent thirty years inside the question of America’s changing crime trends, first as a researcher at the Urban Institute, now as director of the Center on Public Safety at NORC. John Roman has a theory about what actually drove the violence spike of 2020, and an even more specific theory about what’s driving the decline now, one that has less to do with new policing tactics and a lot more to do with $300 billion in pandemic relief money that quietly rebuilt the social infrastructure we lost. In this episode, we talk about why the usual explanations for crime trends –  more cops, more task forces, more local initiatives, don’t hold up against the data. We get into the role police legitimacy potentially played after George Floyd, why the decline has lasted so long, and what the future might look like. John K. Roman, Ph.D. is a senior fellow in the Economics, Justice, and Society Department and directs the Center for Public Safety and Justice at NORC at the University of Chicago.  His research focuses on the economics of innovative crime and justice policies and programs, cost-benefit methodology, and systems reforms, including justice system interactions with substance abuse, public health, adolescent development, housing, workforce development, and education. Dr. Roman has conducted research on behalf of numerous state and local governments, foundations, and federal agencies.

    Using Technology to Improve Crime Analysis with Andy Wheeler

    Today's guest is Andy Wheeler, a renowned criminologist, data scientist, and founder of Crime Decoder. Andy is a terrific voice for understanding the role of technology in analyzing and decreasing crime. We talk through Andy’s work with police departments, including crime trend monitoring,  predictive analytics, focused deterrence, and the challenge of turning data into useful operational decisions. We also discuss the practical realities of artificial intelligence in criminal justice. Rather than focusing on the hype around AI replacing workers or transforming society overnight, Andy walks through how these tools are actually being used today: helping analysts write code, automate repetitive work, build dashboards, and make better use of messy public safety data. This is a great conversation about how the future of criminal justice analysis is already here. Andrew P. Wheeler, PhD and founder of CRIME De-Coder, collaborates with police departments across the United States on custom software and data analytics. His work focuses on predictive analytics, operations research, and policy analysis. See his firm and other resources at https://crimede-coder.com/. Andy also has a recent book, *Large Language Models for Mortals: A Practical Guide for Analysts with Python*, https://crimede-coder.com/blogposts/2026/LLMsForMortals
