Barry Friedman is a DataEthics4All Top 100 DIET Champion 2021, is a Jacob D. Fuchsberg Professor of Law and Affiliated Professor of Politics at New York University of Law, and is the Director of the Policing Project at NYU School of Law. Barry is also a reporter for Principles of Law: Policing at The American Law Institute. Barry's project, The Policing Project, is dedicated to strengthening policing through democratic governance. Policing agencies play a vital role in ensuring a safe and secure society. To see that they function effectively, we must, and do, grant them vast powers. We allow police to restrict people’s freedom of movement, take them into custody, search their person and their property, and engage in surveillance. But these powers are not granted lightly: it is widely recognized that if used wrongly they can imperil the very society that policing officials are pledged to protect. DataEthics4All is proud to call Barry Friedman a DIET Champion 2021 for his work in Data and Diversity, Inclusion, Ethics and Equity in Technology and AI to help the Society.
