In the mid-1990s, the NYPD created a performance management strategy known as Compstat. It consisted of computerized data, crime analysis, and advanced crime mapping coupled with middle management accountability and crime strategy meetings with high-ranking decision makers. While initially credited with a dramatic reduction in crime, questions quickly arose as to the reliability of the data. This volume brings together the work of two criminologists?€”one a former NYPD captain?€”who present the first in-depth empirical analysis of this management system?€”exposing the truth about crime statistic?€?s manipulation in the NYPD and the repercussions suffered by crime victims and those who blew the whistle on this corrupt practice.
