Using data collected through social observations of 188 police officer shifts, the current research examines the time allocated to proactive and reactive activities by traditional and community police officers to assess (a) the extent to which post officers engage in proactive activities, (b) whether these activities differ from the (proactive) activities conducted by community officers, (c) whether post and community officers' activities reflect an emphasis on different functions of policing, and (d) to what extent the activities of both types of officers reflect community policing philosophy.
