It will boil over in the Democrat urban welfare ridden city centers first. Detroit, Chicago, Oakland, Philadelphia, etc. The urban takers will take whatever they can get their hands on. The day the gubmint don't reload momma’s free sh*t debit card, riots will ensue. However, when the takers try to encroach on maker neighborhoods, they will learn very quickly makers tend to have the means to defend themselves, their family, and their property, several times over. Of course the Blue states will be hit the hardest as they have tried very hard to keep residents from having the means to defend themselves. In those states where the criminals are better armed than the populace, you are likely to see some real Mad Max kind of stuff.
Don’t know how true it was but there were stories about people dumpster diving within hours of Sandy.
