The leaks by Edward Snowden reveal a vulnerability in U.S. intelligence since 9/11, triggered by a surge of information collected on people around the world and the proliferation of private government contractors to store, sift and manage it.
Mr. Snowden and other private employees with permission to plug directly into National Security Agency systems have unprecedented access to highly sensitive information””the result of years of pressure to break down the walls dividing U.S. intelligence agencies and share information that might expose the next terror plot.
Thousands of workers employed by government contractors sit side by side with federal workers and hold security clearances that provide access to intelligence databases. The result is a system so enmeshed that government and contract workers are often indistinguishable.
