  Guns, Data, and the Law with Thomas Chittum

  Aug 12, 202645 min

  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

  Aug 5, 202647 min

  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

  Jul 29, 202637 min

  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

  Jul 22, 202637 min

  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

  Jul 15, 202642 min

  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
