This report describes an experimental program in which civilians and police officers work as two-person teams, patrolling fixed "beat" areas in selected urban neighborhoods. These teams work in responding to service calls, aiding regular mobile patrols in their duties, deterring criminal activity and civilian victimization, and developing better community relations. The PAC-TAC experiment takes place at times of high crime and service call activities, in evening hours, seven days a week. This document outlines the background, goals, schedule, personnel selection, and training details. (NTIS)
