Most Americans don't have first hand experience with the lower classes of the population. Their knowledge of them consist of TV, movies and MSM sob stories. Here is some info from an ex-cop that describes them to a "T" and what will happen if and when the SHTF.

I know that most people who read your blogs are aware enough to keep strangers away from their refuge.
But if someone has never lived around these types of people,they may not be aware of just how dangerous they really are.
As I mentioned,they can be charming,cunning and deceitful.They have lived their entire lives off the goodwill of others and The Government and are past masters at pretending to be needy,harmless and "safe". Guile is ingrained in them. I leave you with one short story. In the days after Hurricane Katrina, we were reinforced with officers from other agencies, many states away, who had volunteered to help. (I was not in New Orleans, but on the edge of the hurricane strike) I was partnered with a state SWAT officer from up North. This man was experienced and a "steady hand". As we walked through some of the power blacked-out , sweltering-in-the-heat projects, he turned to me and said: "This is worse than Mogadishu". He was scared and had good reason to be. And this was after only three days of no electricity and relief was just starting to arrive. Think about those same areas after a real failure of services and food deliveries. Good Luck
