An encrypted email service believed to have been used by American fugitive Edward Snowden shut down abruptly August 8, 2013, amid a legal fight that appeared to involve U.S. government attempts to win access to customer information.  Lavabit LLC owner Ladar Levison said he has decided to "suspend operations" but was barred from discussing the events over the past six weeks that led to his decision.    That matches the period since Snowden went public as the source of media reports detailing secret electronic spying operations by the U.S. National Security Agency. The U.S. Department of Justice had no immediate comment.
