Sessions speech to US marshals just now is actually quite revealing. if you didn't listen you may want to.
from Wikipedia," The Marshals Service is responsible for apprehending wanted fugitives, providing protection for the federal judiciary, transporting federal prisoners, protecting endangered federal witnesses, and managing assets seized from criminal enterprises."
think about this in light of the plan. Sessions personally meeting with the heads of the US marshals service to let them know that he and potus have their back and will support them in doing their job.
the US marshals could be a huge part of this and may have just been activated.
