Electronic surveillance: Report of the National Commission for the Review of Federal and State Laws Relating to Wiretapping and Electronic Surveillance"The book provides a background briefing on surveillance technology as it existed in 1976 - although classified devices of the period are not covered. There is a comprehensive description of telephone tapping techniques, wireless transmitters and how their transmissions are concealed, non-audio eavesdropping and tape-recording technology. Coverage is thorough and includes numerous block diagrams but no circuits or schematics. There is a section on counter measures (TSCM) which mostly emphasises how difficult this task is and another on the falsification of recordings." reviewed by John A.
