Emails are not private. A message may have one sender and one recipient  but it can, with little effort, be read by a third party. In fact,  despite the Fourth Amendment’s protections against unlawful searches,  federal agencies do not necessarily need a warrant to read emails older  than six months. 
       Concerns over such government snooping were raised by the American Civil  Liberties Union, which last week noted a “troubling picture” of email  surveillance practices by the Federal Bureau of Investigation and the  Department of Justice. The agencies may be taking advantage of a  component of the Electronic Communications Privacy Act, which requires  warrants only for emails that have been stored on a third-party server  for less than 180 days.
