An interesting statement by Adam L. Silverman over at Balloon Juice:

As someone who’s both done and taught how to do network based targeting, if I was working for Mueller, I’d be advising that he hold off on the American (and British - Cambridge Analytica/SCL, etc) indictments on this stuff as long as possible as I want to see what the rest of the network, especially the Americans and the British portions start to do now that this indictment has been announced. Even the way that DAG Rosenstein made the announcement is intended to get the rest of the network to respond. By stating that no Americans are indicted in today’s indictment, but that the investigation is ongoing, Rosenstein and Mueller are looking to see what the response will be. Specifically, today’s indictment and announcement are intended to get the too cute by half guys like Stone or Parscale or Don Jr or Giuliani and Prince, and the people they’re connected to - inside and outside of the US (remember the Israelis, the Emiratis, and the Saudis appear to be up to their eyeballs in all of this too), to do something in response that can be tracked through all the links and nodes of the network. This also includes Assange and Wikileaks. The counterintelligence officers who work for Special Counsel Mueller have the network mapped out. They are very good at what they do and will be watching to see what happens to and within and throughout the network now that they’ve grabbed a bunch of nodes and links and given them a good, sharp pull.
