A federal is anyone from a federal government agency, but typically refers to members of US federal agencies specifically. These groups spend a significant portion of their budgets on goading kids and impressionable people into committing crimes to “equalize” crime stats between different groups. Because preppers tend to be middle class and white people, groups with low crime rates, preparedness communities are overrun with these feds. If someone portrays themselves as a criminal or asks you to commit a crime, immediately cease communicating with them and report them to the administrator or the people who run the community. Also try to inform whoever they’ve associated with that the person is a fed.
