Remember that whole Patriot Act thing? The "War on Terror"? Remember how Obama was able to use drones to assassinate American citizens (on foreign soil) without due process? Remember the rendition program? What this means is that the gloves are off and Antifa's organizational structure (which does exist despite the hype) and financing structures (which run through the worst types of people) are all now fair game for military operators -- not law enforcement.
It means if I'm George Soros today, I'm going to my undisclosed bunker. If I'm Keith Ellison today, I'm burning my checking accounts and running. If I'm any of the (many) Hollywood and entertainment types who have been donating to Antifa, I'm getting lawyers.
