In Digitize and Punish, Brian Jefferson argues that the US policing and incarceration infrastructure is increasingly marked by new forms of racialized digital criminalization. Examining the incorporation of digital technologies into the criminal justice apparatus, Jefferson shows the central role that digital technology and data science has had in reinforcing racial surveillance practices since the War on Drugs and Crime began more than four decades ago. Jefferson’s timely new book traces the merging of carcerality and technology in Chicago and New York City, unveiling forms of digital racial management that have remained largely obscured from the public.
