#83 (David Décary-Hétu)
David Décary-Hétu is a professor at the University of Montreal and chair of the Darknet and Anonymity Research Centre. Décary-Hétu's research focuses on studying data from offenders who use anonymity technologies like the dark web, cryptocurrencies, and encryption. He reveals that the dark web was originally developed by the military to enable anonymous communication, and that while the dark web and other anonymity technologies pose challenges for law enforcement, they are not the unbreakable havens for crime that are sometimes portrayed in media. The dark web enables new types of crime, but repeated disruptions of dark web markets can lead to some offenders becoming discouraged and quitting.

#80 (Cliff Stott)
Jerry Ratcliffe talks to Professor Cliff Stott, a distinguished social psychologist specializing in crowd behavior, group identity, and public order policing. Stott discusses his background and early life experiences, and how this led him to study crowd psychology and develop the Elaborated Social Identity Model as an alternative to outdated mob psychology theories. Stott's work aims to debunk the myth that crowds inherently lose control and become irrational, arguing instead that crowd behavior is guided by shared social identities and norms. Instead, indiscriminate use of force by police can escalate crowd conflicts, by creating a shared identity of opposition to the police.

#76 (Thaddeus Johnson)
Thaddeus Johnson is a former police officer from Memphis who is now an Assistant Professor of Criminal Justice and Criminology at Georgia State University. He has extensively researched issues related to policing, crime, and racial disparities. Johnson discussed his experiences as a Black police officer and the challenges of navigating his racial identity in that role. He also highlighted the broader systemic racism and inequities in society that contribute to disparities in crime and policing outcomes. Johnson and his colleagues conducted a study examining the effects of police unionization and collective bargaining on police use of force. They found that increased police pay was associated with reduced police killings overall, but this benefit was only seen in non-unionized departments and not for Black citizens in unionized departments. In the episode Johnson discusses police accountability and oversight, transparency around officer disciplinary records, and how to do that without undermining the legitimate labor rights of officers.

#75 (Ian Adams)
Dr. Ian Adams talks about his career in policing, his transition to academia, and his recent policy research paper titled "Fuck: The Police." They discuss the use of profanity in policing and the need for a nuanced approach to regulating it. Adams conducted a survey experiment with police chiefs and sheriffs across the United States, finding a strong national consensus on the issue. He argues that policy should focus on the impact of profanity on public trust and professionalism rather than implementing blanket bans. Adams also highlights the creativity and problem-solving skills of police officers and the challenges they face in their daily work. Just be advised that the episode features strong, and often highly imaginative, language right from the start.
