This country is not that far from turning into a Bosnia or Haiti. All it would take is a serious crash in the economic sector or for there to be a major natural disaster or for our enemies (foreign or domestic) to pull off a huge attack. Civilization is a fragil thing. One minute folks are doing thier day to day routine, the next, disaster strikes and mobs are looting, pillaging and killing for food and water.
Do you realize how long it would take most grocery store to be emptied if the trucking industry was to be shut down or severely curtailed. The answer is most likely a day or two at the most, becuase of just in time purchasing and manufactoring. Large stocks of items are no longer kept in a locl warehouse for the store.
