I think the SHTF has begun. High price of fuel, unemployment, inflation, food supply, etc. constitute the frog in the pot. Wealth envy is another contributing factor. After the folks get really stressed for a while some major event can happen such as a terrorist act, a big one like 9/11, or over stressing the power grid, something that shuts down transportation which might effect food supply and commerce in genera or some problem with the water supply. This could set off civil unrest which could spread. Marshal law could be initiated to put down the civil unrest. Gov't might try to confiscate weapons, etc. to "keep the peace". Who knows where it might go from there.
