The good guys have been mapping the ANTIFA network of people.
They already know who a lot of them are.
The Intelligence Community and Military are really good at mapping out terrorist networks.
My hypothesis is that ANTIFA has been hanging out and recruiting in online chat rooms.
They were in honey pots and they were all being tracked and logged and had no idea.
They don't hangout online as anonymous.
They all use their personal FB, Twitter, etc accounts.
They are fucked.
