Edward Snowden owes some of his successful NSA leaks to weak internal supervision -- the agency simply couldn't detect any suspicious data transfers. Would-be leakers may not be so lucky in the future, though. AP sources claim that US intelligence officials are developing an electronic monitoring system that continuously tracks the activities of government workers with secret clearance. The platform, reportedly derived from an existing military project, would perform both background checks and watch for odd behavior. It could tap into external databases, and investigators could cross-check anything suspicious with social network updates. There would be privacy safeguards in this system, and it would fight both corruption as well as workplace violence. However, critics are worried that non-stop surveillance of the sort could inadvertently leak personal information and discourage freedom of expression -- if not managed properly, the cure could be worse than the disease.
