The article connects the campaign's familiar slogan with the structured intake and review machinery beneath it. Civilian reporting expands national awareness when observations enter a standard process of intake, review, sharing, and analysis. The same find, fuse, identify, correlate, geolocate, predict, and act-faster architecture appears under counterterrorism and broader homeland-security vocabulary. Professional training and reliable information handling make distributed participation useful. ### Marketplace sources - [[articles/The Coming Market for Civilian Spycraft#V.
