My understanding of this is this has been a growing threat against the U.S. by white supremacist and far left anarchists. They've been at this for the past 10 years, recruiting people to destabilize government, using Facebook without censure. There will be plenty more news about this I anticipate that will come to surface. I believe the F.B.I is well aware of them, as white supremacists have been tracked doing these sorts of activities, infiltrating police departments, and such. This is actually real stuff, not conspiracy theory nonsense, even though it sound that way.
