Although most cultures since ancient Egyptian times have practised a form of link analysis with the drawing up of genealogical records its use in network analysis is relatively recent. This is because the complex networks that warrant such tools for analysis are themselves a recent phenomenon, although with some interesting exceptions. Appreciation of the networked nature of our adversaries was probably only articulated as late as 2001 with the publication John Arquilla and David Ronfeldt’s Networks and Netwars.
Social scientists were experimenting with graph theory around human relationships at least as far back as the 1920s and although this had some bearing on later intelligence tools the majority of intelligencers were not interested in complex science but only in understanding the target. Most sources date the beginnings of criminal network analysis to an Anacapa Sciences publication in 1975. Anacapa dominated the US criminal intelligence analysis space at the time so much so that police analysts were frequently called Ancapa analysts. The word Anacapa comes from Native American meaning ‘now you see it now you don’t’ and was the name they gave to an island off the west coast that is usually shrouded in mist but occasionally is revealed by the sun in total clarity.
