The U.S. Supreme Court approved a change to Federal Rule of Criminal Procedure 41 that will allow magistrate judges to authorize searches of computers outside their district, if the location of the computer “has been concealed through technological means.”  This change, unless blocked by Congress, will permit law enforcement to deploy “network investigative techniques” to search computers whose actual whereabouts are unknown.  The Justice Department has long sought this change, but it has been bitterly opposed by civil libertarians and companies such as Google.  The amendments will take effect December 1 unless Congress intervenes.
