After reviewing the capabilities of the ROSA tools, this Resource Guide discusses considerations for using ROSA for the development of criminal intelligence, investigative support, and public safety. A separate section of the Guide discusses privacy, civil rights, and civil liberties considerations that must be protected in the course of using open source analysis for law enforcement purposes. Operational security considerations are discussed in another section of the Guide, which pertains to protections from interference or exposure while engaged in online work. "Deconfliction" is also discussed. This is the process used by law enforcement and intelligence agencies in identifying whether or not more than one agency is investigating the same subject, group of subjects, or criminal organizations. This is followed by a discussion of the dissemination of ROSA-related information or intelligence and the importance of re-evaluating existing policies, procedures, products, and resources. The Guide concludes with suggestions for ROSA-related training. Appendixes contain ROSA-related terms and definitions, ROSA-related case law and guidance, fair information practice principles, and additional resources.
