The State charges that have been filed against the ones arrested so far are reasonably serious, so far as I can tell no Federal Charges have been filed.
This case begs for FBI involvement, you have people crossing state and international boundaries to commit violent terrorist acts in a coordinated manner.
I watched the video, obviously someone is providing financing based on how far away people traveled to get there.
The act was coordinated and had a leadership structure, a couple of times you saw people giving orders and directing the rioting. You also had at least two people who weren’t masked taking pictures and filming the event among the rioters, expect to see the videos online to show others what they’ve done.
You also had duffel bags of rocks and fireworks getting passed out indicating a fairly high level of planning.
Considering how the Feds infiltrated the 1/6 protest and groups like the Proud Boys, etc., you would think the FBI had informants inside Antifa and other leftwing groups, evidently these people are the brownshirts of the Democratic party.
I would think that the FBI is sponsoring these groups.
