When lawmakers passed the ECPA more than 25 years ago, they failed to anticipate that email providers would offer massive online storage. They assumed that if a person hadn't downloaded and deleted an email within six months, it could be considered abandoned and wouldn't require strict privacy protections.
Civil liberties groups say ECPA is woefully out of date in an era when deleting emails is no longer necessary.

The gap in privacy protections for electronic communication has gained greater attention in recent days after the FBI discovered former CIA Director David Petraeus was having an affair by reading his private emails. Petraeus has since resigned.
"While the details of this investigation that have leaked thus far provide us all a fascinating glimpse into the usually sensitive methods used by FBI agents, this should also serve as a warning, by demonstrating the extent to which the government can pierce the veil of communications anonymity without ever having to obtain a search warrant or other court order from a neutral judge," Chris Soghoian, a policy analyst for the American Civil Liberties Union, wrote in a blog post earlier this week.
