Private C.I.A. by John Robb

A strong sign that the nation-state is in decay is the frequency we see announcements of companies that are replicating some of the most sensitive government services. The most recent mover is Walmart, which is in the process of putting together its own intelligence arm (it's being built by a former C.I.A./ F.B.I. officer Kenneth Senser). For those unable to afford their own global intelligence unit, Blackwater's Cofer Black is building one called Total Intelligence Solutions.
