Last week Gen. David Petraeus, the director of the Central Intelligence Agency, resigned in response to what has turned out to be a much bigger scandal than it first appeared. We've gone from a complaint to the FBI by one woman, Jill Kelley, over harassing anonymous email messages that were sent, it turned out, by another woman, Paula Broadwell (who was, of all things, Petraeus' biographer) that exposed the affair Petraeus had had with the latter and which has now embroiled another senior military man, Gen. John Allen, because of email sent to the first woman.
