beans and bullets- a bit simplistic
be sure to add big body bags and bleach to your siege supplies of beans and bullets
you’ll have to do something about the dead rotting bodies of the men women and children you kill. I assume when you shoot looters with children you will also shoot the children, and that you have thought this through
Bodies piled up on your lawn and outside your doors and windows will be a health hazard to you. Since we are talking months, maybe years here
The dead bodies of those you shoot will also show looters with guns (who will form mobs) the homes that have something inside worth killing for
God forbid! However, making it real: Backhoe and plenty of lime. No body bags needed. Also... make sure your trench is deep and below your well water supply.
