I hear from anonymous correspondents that the following technique has been successfully deployed among some militia members and cypherpunks who fear raids on their private property. Apparently the technique was originally invented by a biotech lab that the FDA was planning to shut down in an uncivil manner when Kessler first came to power. The lab was never raided. Preliminary: choose a suitable viral agent. This may range from a short, severe flu to Eubola, depending on the level of deterrence desired and safety precautions you have available. Long-latency debilitating diseases have also been suggested as an especially effective deterrent that puts the property owner at less risk of detection. The property owner must obtain both the agent and an effective vaccine. Step one: immunize household members against this agent. Step two: create "tamper avenging" packages around the house. Make them very suspicious looking (gun lockers, boxes labeled "Danger: Toxic Materials", file folders labeled "Assassination Schedule for December", and so on). Don't put them where guests, pets, and so on can get to them, but in places where the thugs will look. Step two (detail): the tamper avenging package contains an invisible film of the viral agent in fluid adsorbed to a suitable carrier. The carrier is a clear, thin film of sponge-like material that produces a fine aerosol of virus containing fluid drops when disturbed. When the package is opened and disturbed, the aerosol quickly shoots and and spreads throughout several surrounding cubic meters. Persons unprotected by immunization or breathing masks are contaminated with high probability. I've heard unconfirmed rumors of a special sponge material that lasts for days, infecting a variety of government personnel and contractors who come in contact with the evidence, and in some cases, depending on the particular vector, people they in turn come in intimate contact with. Obviously I have not provided enough useful information in this post to propery implement this technique. Don't try this at home without the help of paid professionals (who I hear are making a killing now with the recent spate of raids against militias, patriot groups, cypherpunks, and so on).
