Whereas some departments have cut their information technology (IT) investments and staffing as a way to avoid cutting sworn officers, others have increased their investments in IT, believing it can serve as a force multiplier, increasing the efficiency and effectiveness of the department. IT has become increasingly integrated into modern police organizations, particularly for systems related to records management, dispatch, crime investigation, personnel records, information sharing, fleet management, automated booking, and resource allocation. But the trade-offs among personnel, technology, and costs are not straightforward. With this report, the authors explored the rationale and evidence supporting the idea that IT investments can increase efficiency in policing, and do so cost-effectively. The correlation modeling suggested both expected and unexpected relationships between IT and efficiency. For various reasons, the efforts to carry out a full statistical analysis of police IT use matched with activity types using existing survey data did not succeed. However, they did yield insights that are relevant to the design of future efforts to assess the effects of IT systems on law enforcement performance. |
