NSA technical managers should have realized that suitability to task was an issue very early in their evaluation process -- in fact, as part of due diligence during procurement.
The fact that their design would have required 1000's of Snowden's, let alone that 1000's of Snowden's would have had this breadth and depth of access should have been clear long before implementation.
If they didn't understand that during implementation, their security people should have during life cycle. If their security people did not, then counterintelligence people should have.
If I worked for the FSB or the Chinese MSS the first question I would be asking myself is: "How much of what Snowden has is real, and how much of it is horsesh!t I am being deliberately fed?" American Intel cannot possibly have failed on this many levels."
And, given that we know that NSA lies to Congress -- even to the Intelligence Committees -- I would be asking myself that same question as a Senator or Congressman.
