...I don’t see it that way...police will abandon their posts and go home to look after their own families...crimnal motorcycle gangs will prey on the weak...after they’ve taken the all the easy pickings locally they’ll begin to roam the countryside...I’d rather prepare for the worst and hope for the best.
Motorcycle gangs will be the most dangerous and effect looters/pillagers during any prolong SHTF event.
