The linked story tells of a Florida prepper on the run from the FBI due to a warrant for constructing dangerous devices. The article points out that one of his prepper group was a “FBI employee.” Read that to mean, “Confidential Informant.”
For the legal protection of your family, friends, and group, whatever you do, DO NOT discuss, much less actively construct, anything against the law. Especially be congnizant of someone in your group trying to maneuver you into that kind of conversation or activity! Also make sure all your purchases comply with existing law in your State as well as federal law.
If anyone in your NPT starts advocating in any way circumventing or otherwise doing illegal things, eject them post haste. Chances are they’re a CI trying to get you to do something that will get you arrested….while he, she, they or it moves along to the next well-meaning but naive group.
This isn’t a game, people.
