Abstract: This essay is a personal reflection on John Long’s keynote address at the BCS People and Computers meeting in Nottingham in the summer of 1989. I try to locate the paper’s purpose and significance within the history of human-computer interaction (HCI), both prior to 1989 and subsequently, and particularly with respect to the abiding questions of what sort of enterprise HCI is, and of what sorts of knowledge it uses and produces.

In recent years there has been a move within police services towards a proactive and intelligence-led style of policing. This has coincided with a recognition of the value of local policing solutions and the importance of the intelligence function at the local area command level. This paper uses a combination of hotspot analysis within a geographical information system (GIS), a hotspot perception survey of police officers, and small focus groups to assess the intelligence dissemination process for high volume crime on three Nottinghamshire subdivisions. The results indicate a variable result depending on crime type explored and the study has implications for the dissemination of high volume crime intelligence within police services.[/p] [ABSTRACT FROM AUTHOR]
