Artificial Intelligence Ethics and Predictive Policing: A Roadmap for Research

Against a backdrop of historic unrest and criticism, the institution of policing is at an inflection point. Policing practices, and the police use of technology, are under heightened scrutiny. One of the most prominent and controversial of these practices centrally involves technology and is often called "predictive policing." Predictive policing is the use of computer algorithms to forecast when and where crimes will take place — and sometimes even to predict the identities of perpetrators or victims. Criticisms of predictive policing combine worries about artificial intelligence and bias, about power structures and democratic accountability, about the responsibilities of private tech companies selling the software, and about the fundamental relationship between state and citizen. In this report, we present the initial findings from a three-year project to investigate the ethical implications of predictive policing and develop ethically-sensitive and empirically-informed best practices for both those developing these technologies and the police departments using them.

Winning the Battle, Losing the War

At least since the Industrial Revolution, humanity has had a troubled relationship with technology. Even while standards of living have skyrocketed and life expectancies lengthened, we have often been shocked or dismayed by the unforeseen disruptions that technology brings with it. I suspect that a major source of this myopia is the naivete of one popular view of technology: that technologies are merely neutral tools and that our engagements with particular technologies are episodic or, in the words of Langdon Winner, brief, voluntary, and unproblematic. I think view is simplistic – and appreciating both the consequences of longer-term technological policies and the interplay between a technology and its social context can help us anticipate these negative consequences. In particular, we should appreciate how even an efficient and reliable technology can nurture social circumstances that will undermine the very goals that technology is meant to serve.

Fairness in Predictive Policing

Machine Learning has become a popular tool in a variety of applications in criminal justice, including sentencing and policing. Popular media has brought attention to the possibility that predictive policing systems cause disparate impacts and exacerbate social injustices. However, there is little academic research on the importance of fairness in machine learning applications in policing. Prior research has shown that although machine learning models handle some tasks more efficiently, they are susceptible to replicating systemic bias of previous human decision-makers. While there is much research on fair machine learning in general, there is a need to investigate fair machine learning techniques as they pertain to the predictive policing. Therefore, we evaluate the existing publications in the field of fairness in machine learning and predictive policing to arrive at a set of standards for fair predictive policing. We also review systematic evaluation methods and potential techniques to improve these technologies going forward. We suggest that police departments take stock of the influence of systemic bias in policing practice before incorporating techniques such as predictive policing. Lastly, in any area, including predictive policing, the pros and cons of the technology need to be evaluated holistically to see if the new technology should exist in this area or not.

Police Ethics and Police Technology

The first professional police force was founded in Boston, Massachusetts in 1838. Since that time police have long played a central role in the promotion of safety and security in the United States. But a growing chorus of critics is questioning the place of policing in maintaining social order. Among the concerns being voiced are that police work increasingly violates civil liberties, that policing is racially biased in ways that oppress marginalized people, and that the scope of police work outstrips their expertise. Emerging policing technologies can either ameliorate or aggravate these concerns. In this course we will investigate, through the methods of moral philosophy, the moral foundations of policing, some recent ethical controversies about the role and conduct of police in society, and the appropriate role of technology in policing. Topics include an introduction to ethical issues in artificial intelligence, the role of police in society, institutional critiques of policing and big data technology, police discretion, predictive policing, surveillance and data collection, non-lethal weapons and police use of force, and future directions in policing and policing technology.
