Spy Technology Modern Marvels : Season 6 Episode 21

In the name of national security, the governments of the world have developed devices that could render privacy a quaint anachronism. But could this Orwellian nightmare ever really come to pass? Spy Technology traces the evolution of the tools of espionage over the past century, from drop boxes and rudimentary codes to the tiny, high-tech devices that are already far more prevalent than most people imagine. Get an up-close look at some of the most important spy equipment ever made, and hear James Bond-esque stories of their use in the Cold War and afterwards. And find out why there is no technical reason why the lessons learned spying on other countries might soon be put into use internally. It is no longer a question of feasibility, but of ethics?
