The police are products of the culture, too. Tattooed, pierced, bulked-up and narcissistic. At some point we should stop being surprised by armed citizens attacking police. It's just a sign of living under the weight of oppressive govt. Only you're just not supposed to rebel, because there's plenty of govt welfare out there for ya. Never mind that you would rather have a standard of living that allows you to live up on the bluff with the govt employees instead of down below next to the slag heaps.
Something, some kind of propaganda will be needed to put fear into our minds. Something to remind us of the overwhelming power of the oppressor over every aspect of our lives, including our deaths. What will that be? Gladiatorial games?
