They will rob and kill everyone they can before they starve, though. Hell, they do that now. There WILL be another civil war. And it will probably dwarf the first one. Not many folks want to admit that it’s coming,yet, but a lot of people know it.
I pray people are prepared to defend themselves. Our neighborhood is close and many of us have fully prepared. A good number of ex-military. I will say this, we don't fear Zombie attacks.
Yes everyone who is dumb enough to live in intown Atlanta is going to have their hands full when the SHTF. We are out in the burbs and we have finally determined that even with a bad attitude and plenty of weapons and ammo our house is not defendable. We are looking for a place with enough acreage for a clear field of fire. Plus up in the mountains of N GA there is no cultural diversity.
