Janet Reitman writes: Early one morning last December, Glenn Greenwald opened his laptop, scanned through his e-mail, and made a decision that almost cost him the story of his life. A columnist and blogger with a large and devoted following, Greenwald receives hundreds of e-mails every day, many from readers who claim to have “great stuff.” Occasionally these claims turn out to be credible; most of the time they’re cranks. There are some that seem promising but also require serious vetting. This takes time, and Greenwald, who starts each morning deluged with messages, has almost none. “My inbox is the enemy,” he told me recently.

And yet, Greenwald still didn’t bother learning security protocols. [Continue reading…]
