Email Users Can't Count On Privacy Protections
There's one safe assumption on the Internet: Email isn't safe. One of the lessons from the unfolding case of the former director of the Central Intelligence Agency, David Petraeus, is that privacy protections for even the most sophisticated users of consumer-email services actually protect very little.
In response to a Florida woman's complaints that she had received threatening emails, the Federal Bureau of Investigation gained access to the emails of Paula Broadwell, a writer who allegedly set up Gmail accounts under aliases to conduct an affair with Mr. Petraeus. To do so, the FBI received search warrants from a judge, according to U.S. officials. But other clues in the FBI investigation could be garnered without a warrant in an era when personal communication has shifted to centralized websites like Google and Facebook, where messages rarely get truly deleted and all online communications carry a number of digital footprints. "If the director of central intelligence isn't able to successfully keep his emails private, what chance do I have?" said Kurt Opsahl, a senior staff attorney at the Electronic Frontier Foundation, a digital-liberties advocacy group.
