The Coalition States of Rifts Earth has in place a program by which they register and monitor psychics within their territory. While the CS is a Nazi-themed, human supremacist nation with ambitions towards genocide, this fairly reasonable step hasn't been explicitly taken by other nations. But something occurred to me in considering this... while it will let the CS adequately track "mutants" who have psychic powers, it can also serve as a registry of those who may give useful psychic information... be it those who can be conscripted for specific tasks, or hints of what is to come.
