Critical Understanding of Predictive Policing (CUPP) is an international project running from 1 February 2021 until 31 January 2024 (prolonged until 31 January 2025) funded under the NordForsk Research and Innovation Programme on Digitalisation of the Public Sector (project no. 100786). It brings together seven partner organisations from five European countries - Denmark, Norway, Latvia, Estonia and the United Kingdom - to explore the digital transformation of law enforcement and its impact on crime detection and prevention. It aims to identify and critically assess the effects and impact of data-driven police technologies on society and end-users.
