Incidents and emergencies can severely tax the capacities of law enforcement agencies to respond in a rapid and coordinated fashion. Public safety officials can perform their jobs more efficiently by using Computer-Based Information Systems (CBIS), which include hardware, software, database, network procedures, and people, all organized to do a specified job. Acquiring information technology resources can require more personnel to supervise and maintain the systems, possibly resulting in shifting law enforcement officers from street duty to in-house, non-law enforcement functions. The article suggests an alternative system design involving deployment of more technology, using wireless technology to a greater extent in the field. One way to coordinate the efforts of emergency personnel during crisis situations is to use CBIS to facilitate cross-communication in assessing quickly and effectively the degree of seriousness of an emergency call. The article includes two case studies that illustrate ways CBIS technology helps to improve the effectiveness of public safety agencies. It also discusses cost and funding issues. References
