Protecting Life is about the moral principles, at the individual and institutional level, that should guide and restrain police use of deadly force. Beyond simply identifying those principles, Ben Jones translates them into law and policy through extensive engagement with social science research. Protecting Life clarifies the obligations of police, explains how current police practices fall short of those obligations, and outlines concrete strategies to reduce policing killings without compromising public safety. Written in an accessible manner, the book will be of interest to scholars, practitioners, and the public alike.
