Yep, the cops will be going door to door to collect supplies in some areas.
Heck people turn feral in about 15 mins as it is, give them a week without food and they’ll be desperate. Most people don’t have more than a couple days of food in their house.
I’ve gone 8 days without food due to a medical issue. Lost a bunch of weight very quickly.
After a week, half of the cops will be guarding the mayor and other big shots. The other half of the cops will have deserted their posts to guard their own families. We will be on our own. Have you read the essay I wrote and linked a few above, “When the music stops?”
