Sheldon Pacotti makes the case in Salon that a completely open society, rather than a government crackdown, may be the best chance for surviving terrorism by means of nanobots, engineered biological viruses, or other self-replicating technology.
"What happens, in a police bureaucracy, if someone releases a nanotech plague into the environment? If the police can suppress information on the structure of the nanobots, then only a handful of government bureaus and hand-picked researchers may be allowed to work on a cure. Millions could die waiting for the bureaucracy to solve the problem. On the other hand, if the molecular structure of the pest is published worldwide, anyone with the expertise could help design defensive technology."
