Omar Garrison is a well-accredited newsman and this is a protest against privacy invasion of all kinds, certainly not as thoughtful as Alan F. Westin's Privacy and Freedom (p. 553)--he refers to Dr. Westin's work throughout--but more on the level of Vance Packard, Myron Brenton and Martin Gross, all of whom have covered aspects of the question as they occur today. Rampantly, flagrantly. Mr. Garrison deals with this ""massive intrusion"" in terms of wiretapping (begun back in 1895) and monitoring devices and instruments of interception, of personality probes and polygraphs, of the misuse and dispersion, of federal files, of the mails, etc. He is particularly informed on the supersnoopers of the U.S. Internal Revenue Bureau, the F.D.A. and the F.B.I. where abuses proliferate. Sometimes he strays--the medical experimentation in the interests of cancer research on the indigent in a Brooklyn hospital which recently made headlines has little or nothing to do with spy government; or Garrison's intention which is to ultimately show that ""lawless law enforcement"" leads to the police state. He beefs up the argument with a great deal of material from respectable sources, and the only question is whether the market has been overexposed to this kind of expose.
