A profile of Edward Snowden

The federal government monitors threats to national security with the help of nearly 500,000 private-sector employees. Private firms have access to a great deal of top secret information.

This month, an employee of one of those firms -- Edward Snowden, formerly of Booz Allen Hamilton -- lifted the shroud of secrecy off the National Security Agency and its massive data collection program.

Francis Rose, host of "In Depth with Francis Rose," discussed Snowden's background and other top government issues with Capital Insider.
