The FBI is in charge of criminal investigations of civilian U.S. intelligence workers, even if the alleged crime occurs on an NSA base.

Aside from the © few dozen documents published by The Guardian and The Washing- ® ton Post, what else had Snowden stolen?

To begin with, they needed to find out how many documents from the center had been copied and taken by Snowden.
