What should we do about the police? There's no American institution that is more controversial. We're swimming in proposals for reform, but most do not tackle the aggressive culture of the profession, which prioritizes looking up bad guys, loyalty to other cops, and not taking flak from anyone on the street. Far from improving public safety, this culture poses a danger to citizens and cops alike. Neil Gross brings readers deep inside three unusual police departments-in Stockton, California; Longmont, Colorado; and LaGrange, Georgia-whose chiefs sought to replace that culture with something better: models focused on equity before the law, social responsibility, racial reconciliation, and the preservation of life. Informed by research, unflinching, and by turns gripping, tragic, and inspirational, Walk the Walk opens a window onto what the police could be, if we took seriously the charge of creating a more just America.
