Ron S, you are right to a point. It depends on the SHTF time. If it is a total collapse with civil unrest or civil war then hungry people will go everywhere. A Recession and a Depression will not make the population go nuts to the point of killing people, there will be some nut not like a SHTF civil unrest total collapse.
I think that what is coming will start with a Recession then go to a Depression which will bring civil unrest and a total collapse.
