This chapter explores the evolving role of AI and jurimetrics in criminal proceedings, highlighting their potential to enhance predictive justice and key challenges. It defines predictive justice and examines the foundations of jurimetrics and AI, including machine learning, data analytics, and NLP. Empirical findings reveal the effectiveness and limitations of tools like COMPAS, PredPol, and TrueAllele, emphasizing concerns about bias, transparency, and judicial discretion. The chapter discusses AI's practical applications in law enforcement, courts, and legal procedures, illustrating how AI can streamline processes but also perpetuate biases. Ethical considerations, such as privacy threats and accountability, are critically examined. Trust dynamics, including stakeholder engagement and oversight, are stressed for responsible AI adoption. Future directions focus on advancing AI technologies, implementing robust policies, and prioritizing ethics to balance innovation with justice.
