I'm not sure if this twitter discussion was posted yet. The woman in the discussion provides the letters as proof. There were others in the discussion confirming similar stories. My nephew also had a conversation with local police officer today(their kids are friends) and officer said he was notified to be prepared to enforce keeping residents in their homes. We are in rural New England. No timeframe given. Although in the above letters it says anytime between 3/16 and 4/28 for the shutdown.
