How much food is delivered to cities, all sized cities, by trucks which require gas or diesel pumped in from a far and then pumped into the trucks via electrically powered pumps? How long will the current supply of food in any citiy last without trucking? Laugh all you want, the scenario is horrific to contemplate, and quite real.
A maximum of two days but if power is out, riots will start in the inner cities before the first day is over and there won't be enough police to stop it, the police will see they are completely outnumbered, and go home.
there will be massive violence...anyone with anything will be a target......
