• “the determination of the legality of the surveillance can appropriately be made in ex parte, in camera proceedings”
• court cannot grant damages when plaintiff waived any attempt to show actual harm but nevertheless sought damages under the Act
• no merit to claim that statute violates presumption of innocence; whether underlying indictment later found invalid not significant since crime complete when firearm carried in interstate commerce by a person then under indictment
• inadvertent surveillance of American citizen admissible in warrant-less wiretap intended for foreign intelligence purposes
