That's again why Antifa uses the organization system they do. It's harder for one cell when caught and facing prison to rat on other cells since the members in trouble really don't know who the people in other cells are. Sort of like people posting on the Internet using aliases. Again, this came out of the results the radical Left saw in the 60's and 70's. They realized that it was too easy for the FBI to infiltrate them and spy on them, so they actively worked to create methods to eliminate that.
