ESSAYS ADDRESS THE PROBLEMS OF POLICE PATROL WORK, POLICE-CITIZEN ENCOUNTERS, THE SOCIAL ORGANIZATION OF ARREST, POLICE CONTROL OF JUVENILES, ROUTINE POLICE ARREST PRACTICES, PUBLIC DRUNKENNESS, AND POLICE WORK WITH TRAFFIC VIOLATORS. SELECTIONS ON POLICE CORRUPTION FOCUS ON CASE STUDIES OF POLICE CRIME, PARTICULARLY IN NEW YORK CITY. POLICE BRUTALITY AND INCIDENCES OF POLICE HOMICIDE ARE ALSO DISCUSSED. ESSAYS PROVIDE INSIGHT INTO THE NATURE OF POLICE PATROL BEHAVIOR AND THE TYPES OF CITIZEN-INITIATED PROBLEMS THAT POLICE PATROL OFFICERS CONFRONT. THE PAPERS ILLUSTRATE THAT, IN ENCOUNTERS WHEN OFFICERS CAN CHOOSE AMONG A VARIETY OF DISPOSITIONAL ALTERNATIVES, EXTRALEGAL CRITERIA (SUCH AS DEMEANOR AND RACE) MAY DOMINATE POLICE EXERCISE OF DISCRETION. MOREOVER, THEY SHOW THAT CORRUPTION IS PRESENT IN NEARLY ALL POLICE DEPARTMENTS THAT HAVE BEEN STUDIED, ALTHOUGH THE EXTENT OF CORRUPTION VARIES AMONG DEPARTMENTS. STUDIES CITED IN THE ESSAYS SUGGEST THAT UNNECESSARY FORCE BY PATROL OFFICERS IS FAR FROM UNCOMMON. ESSAYS CONTAIN FOOTNOTES, TABULAR DATA, AND/OR REFERENCES. (WJR)
