Its worth looking through these letters if you've ever heard some CALC suckhole whinge about activists using cellphones,night vision,GPS,etc. "Historically, it has been essentially impossible to adequately motivate an assassin, ensuring his safety and anonymity as well, if only because it has been impossible to PAY him in a form that nobody can trace, and to ensure the silence of all potential witnesses. Even if a person was willing to die in the act, he would want to know that the people he chooses would get the reward, but if they themselves were identified they'd be targets of revenge. All that's changed with the advent of public-key encryption and digital cash. Now, it should be possible to announce a standing offer to all comers that a large sum of digital cash will be sent to him in an untraceable fashion should he meet certain "conditions," conditions which don't even have to include proving (or, for that matter, even claiming) that he was somehow responsible for a death."
