NSA employees spied on significant others
These employees weren't surveying potential terrorists or enemies of the state - the targets of spying abuse, in a majority of the 12 violations, were the employees' significant others.
In one instance, a civilian NSA employee who suspected her husband had been unfaithful queried a foreign telephone numbers she'd discovered in her husband's cell phone. The query resulted in her husband's voice collection. The NSA inspector general determined a violation had occurred, referring the matter to the agency's general counsel, but the employee resigned before she was formally disciplined.
