From the recent essay "Anarchy" by T.C. May:
The use of encryption by "evil" groups, such as child pornographers, terrorists, abortionists, abor- tion protestors, etc., is cited by those who wish to limit civilian access to crypto tools. We call these the "Four Horsemen of the Infocalypse", as they are so often cited as the reason why ordinary citizen-units of the nation-state are not to have access to crypto. A problem with the Four Horsemen is the various definitions currently in use on the Net. Two of them are generally agreed upon: Drug Dealer and Terrorist. Usually either Pedophile or Pornographer is the third. The fourth varies the most: Tax Evader, Spy etc. Abortionist and Abortionist-Killer are new prospects. Who were the Original Four? (No, I'm not asking about White, Red, Black and Pale.) Mats quit
