Here's a thought that might make even the most conscientious e-mail user nervous: "When the CIA director cannot hide his activities online, what hope is there for the rest of us?"
The American Civil Liberties Union posed this question in a recent blog post. The group, of course, was referring to the scandal involving David Petraeus, who resigned as head of the spy agency after the FBI uncovered e-mails indicating he was having an affair with his biographer, Paula Broadwell.
The story has gotten lots of media attention, in part for its soap-operatic qualities. Less discussed, however, at least outside the technology press, is what this e-mail-based investigation says about privacy and surveillance in the digital age.
