A number of American cities have elected prosecutors who promised progressive law enforcement, focusing as much on police accountability as being tough on crime. In St. Louis, that prosecutor was Circuit Attorney Kim Gardner, who was elected in 2016 following the fatal police shooting of Michael Brown in the suburb of Ferguson. Gardner came into office pledging to reduce mass incarceration and promote rehabilitation over punishment.

But from San Francisco to Philadelphia, prosecutors like Gardner have faced pushback from the police and, in several cities, from their own courtroom assistants. Politicians and voters have tried to remove some of these prosecutors from office — and, in a number of cities, they have been successful.

Murphey’s resistance to Gardner — Chigurupati’s boss when Vincent’s case went to trial — was unusual and, perhaps, extreme. By his own account, he was willing to help murder suspects walk free to make a point, even if he arrested them and believed that they should be behind bars.
