Many books that deal with spooklore carry the look of a catalog. To a degree this is unavoidable:
The hardware bears the message. A picture of a microtransmitter stuck to the end of a thumbnail
speaks silently of its potential. In fact, perusing a catalog from the typical "police supplier" tells
much of what is possible, from both attack and defense, with modern bugging technique. The U.S.
Embassy fiasco in Moscow highlights a climate of technological subterfuge that demands a hardnosed
approach to surveillance, since we have come to feel its cold hand in ever-more aspects of
daily life. Those who refuse to learn the etiquette of attack and defense disarm themselves. They
deserve to suffer their ignorance.
