One Week in Heron City follows Chief Laura Harrison's through her first week on the job in this fictional city of 400,000. We invite you to eavesdrop and see how law enforcement agencies might eliminate pre-established mentalities and see problems in a new light. This "New Perspectives in Policing," September 2009, is one in a series of papers that will be published as a result of the Executive Session on Policing and Public Safety; for the other part of this case study, see NCJ-227664 and 227665.
