In the fifth episode, Dr Lucas Melgaço interviews Dr Fieke Jansen (just before she defended her doctoral thesis) on her research on data-driven policing, where she reflects on how the datafication of society changes the understanding of police power, crime and justice. She offers her insights on how technology and data are used in everyday operations of policing, on the concepts of predictive policing and data legitimacy, and on how critical realism has been applied in her doctoral research.
