37 down-loading documents for some 10 months before he copied these documents. When I discussed the chronology of the copied documents with a former government official briefed on the investigation, he suggested that Snowden’s purpose may have changed between 2012 and 2013. When I asked him what might have induced the change, he replied “That is one of the unanswered questions.” That Snowden only took these two whistle-blowing documents at the tail-end of his 9-month operation, and after he had contacted Poitras and Greenwald, suggests he may have had another motive prior to contacting journalists. In light of this chronology, the investigation had to consider the possibility that his whistle-blowing was, partly if not wholly, a cover for another enterprise. The investigation soon ran into another serious issue: his access. Snowden had described to journalists a situation in which he had access to“ millions of records that [he] could walk out the door with at any time with no accountability, no oversight, no auditing, the government didn’t even know they were gone,” but, as it turned out, he was not among the limited number of individuals at the Center who had access to these documents, The NSA’s and Booz Allen’s employment records showed that Snowden had not yet completed his requisite on-the- job training at the National Threat Operations Center in Hawaii when he carried out the theft.

Somehow he converted his proximity to access. This lack of access could not be ignored in any law-enforcement investigation. Consider if a hundred top-quality D-flawless diamonds were stolen from locked vaults at Tiffany’s by a recently- hired trainee who, it turned out, did not hav
