'Danger Close': The Need for a Nationwide Deconfliction and Notification System for All Law Enforcement Agencies [open pdf - 980KB]
From the thesis Abstract: "To prevent friendly fire incidents and avoid duplication of effort, law enforcement agencies in the United States use multiple deconfliction systems to register investigative targets and notify outside units and agencies of proactive undercover operations. This research reveals that investigators are confused about which of the main systems to use in certain areas and that the use of multiple systems prevents investigators from gathering data on friendly fire incidents and restricts collaboration between agencies that are targeting the same criminals. Having one central deconfliction system for use by federal, state, local, and tribal authorities would make law enforcement officers' jobs safer and would facilitate information sharing among the different units and agencies, leading to greater collaboration and more successful outcomes."
