IMHO, it seems to be because someone or something is trying to get the American people to go feral. Every goddamn piece of media we have is about how the Other is crazy, evil, bad, insane, out to get you! For values of Other equalling: White, Black, Gay, Muslim, Christian, Conservative, Liberal, Government, Civilian, Military, Policeman, Criminal, Rich, Poor, Corporation, Entrepreneur, Truther, Skeptic, Foreign, Domestic, Male, Female, everything. Just everything.

ALL OF IT. It's a giant psy-op. It's been ramping up for the past 10 years, slowly and the speed of the thing is now increasing.

There's an encouraged psychological binary being formed, with an undertone of mindless insanity being promoted and it's getting stronger, and louder, as the days go by. People are being induced into going crazy IMHO and as part of that crazy they hang on, to extremist levels, the bits of Not Other that they are comfortable with. It's all they have left to cling to as a point of Reference Sanity in the midst of this bombardment of mindless terror and chaos and Other colored hatred.

Policemen and women, as authoritarian personalities, will cling to and enforce - radically - the rules and mindsets they have, even when they go against common sense and rules of humanity, as they are the same victims of this all pervasive Otherism and the subsequent desperate clinging to Reference Sanity. Which, sadly, means the fomenters of Otherism are winning. :-\

And, quite frankly, I'm not entirely sure this is just limited to America. I see it happening in other country's media too.

Fuck that. Fuck it all. We all bleed red.

All we have to protect ourselves is love. All we can give to the machine is based on fear. And the propaganda is all about fear these days. Fear of Other.

TL; DR - Police, like everyone else, are being manipulated into a binary system of Otherism, for the purpose of fomenting utter chaos.
