168 Despite all the potential flaws in it, the outsourcing system, ii seemed to work until 2013. It even featured a revolving door through which Booz Allen, for example, hired retiring executives from the intelligence services, such as ex-NSA director Michael McConnell, R. James Woolsey, a former director of CIA, and Lieutenant General James Clapper (ret), who later served as Director of National Intelligence.

This was what Snowden did when he moved from Dell to Booz Allen Hamilton in 2013. Despite its security flaws, outsourcing provided a number of advantages to the NSA.

Finally, it used less NSA resources. Since these information technologists were only temporary employees, they were not entitled to military pensions, medical leave and other benefits. It was a system which effectively replaced military careerists with free-lancers. The irony of the situation was that the NSA h
