Antifa are trying to move the riots out of the cities, but their fundamental problem is they have few supporters so the inverse=squared law kicks in and bites them. They can easily target one suburban neighborhood, but they cannot cover much territory.
This is why it is so important for people to talk to neighbors, to patrol the neighborhood looking for weapons stashes, and to chase away the bicycle scouts when they appear to guide troublemakers in.
