Roving bands of starving people with no concience can do a lot of harm. They will fan out over the countrysides and steal what the rest of us have put away.
If the Martial Law enforcers have the roads closed then they will have to do it on foot. Bands of roving looters in this part of the country wont go home, I can tell you that. What we have is staying right here. I would advise you to invest in a ten pound insurance policy and several thousand amendments for it.
