My plan is to get to know my neighbors and organize.
Depending on the scale of the crisis I would organize my nearest neighbors, then the block, then the surrounding 100 or so blocks, and so on. I would call community meetings to elect emergency reps/leaders, organize security, provide food for the hungry, send trucks out to trade for food in the country if needed, etc. Business owners would rapidly organize to protect their property. I’m sure employees of those businesses have a stake in their futures as well.
We are Americans! We will not hide in our homes as one neighbor after another is attacked by mobs. Law and order would be restored pretty quickly (well, maybe not in NOLA).
OMG, I am turning into a Community Organizer.
Would?
Now is the time.
