Fusion centers have the ability to fuse and analyze information from multiple sources, jurisdictions, and disciplines into a regional or a State picture and identify events that may be related. FLO programs provide an effective way for law enforcement agencies to engage with fusion centers since FLOs serve as liaisons between their agency and the fusion center. FLO programs are a valuable tool for supporting fusion centers to build their relationships with State and local law enforcement. The FLO program enables fusion centers and participants to establish a wide and deep information-sharing network. This article presents an overview of the FLO program structure and their effectiveness in expanding the gathering of information regarding behaviors and incidents associated with crime and establishing a process to share information to detect and prevent criminal activity, including domestic and international terrorism. 1 note
