From Foreign Policy:
Sometimes, the cure is worse than the disease. Especially when it’s the government that’s doling out the medicine. This is what happened when Washington attempted to improve the way its security agencies vetted hundreds of thousands of workers needed suddenly after the 9/11 attacks to pursue counterterror tasks and oversee heightened secrecy requirements. Soon after its hiring binge began, the government’s ambitions collided with a creaky system for conducting the background checks needed to approve job applicants for security clearances.
