Law enforcement agencies increasingly demand sophisticated information technology (IT) capabilities to support their operations. These capabilities depend on records management systems (RMSs), which maintain agencies’ case histories, and computer-aided dispatch (CAD) systems, which maintain agencies’ calls for service and call response histories. There are also increasing demands to share information with regional, state, and federal repositories of criminal justice information. While substantial progress has been made in improving the information-sharing ability and affordability of key law enforcement systems, many barriers remain. This report reviews progress to date, the sizable barriers remaining, and approaches to overcoming those barriers.
