A company named 'USIS' has a contract to do background investigations of people who have applied for jobs that require a top-secret security clearance. I believe that USIS performed the security investigation on Snowden. However, USIS itself has been under investigation for doing shoddy work, cutting corners, etc. So, Snowden slipped through the cracks -- he never should have been given a top-secret clearance.
Heads will roll. I would not want to be the CEO of USIS right now.
