Police brutality, both racially motivated and otherwise, really needs to be seen as an expression of sexual sadism disorder.
White supremacy has always had a very strange thing going on with black sexuality, as John Howard Griffin discovered to his disgust while disguising himself as a black man and travelling in the South.
But in addition, the very nature of white-on-black violence seems founded on humiliation, degradation, torture, domination...
Lynchings, of course, were all about mutilation, depravity and castration. This was deflected by an obsession with the 'purity' of white womanhood. A trail of violated, mutilated and hung corpses followed in its wake.
This succeeded the old paradigm, where slaves were raped, tortured, burned alive.
And then there was the confectioner in Richmond who beat his four year old slave so badly, she died the next day. Ian Brady would surely have approved.
Am I implying that white racism, at least in the American context, is based on sexual depravity? Yes. And like all sexual abuse, it is both conducted in plain site, and enabled by a great many accomplices.
All the posturing, macho swagger and special pleading of US police unions smacks of the same self-aggrandising bullshit of a Jimmy Savile, a Harvey Weinstein, any number of pervert priests, perhaps even a Donald Trump.
Sexual abuse went hand in hand with destroying both body and soul.
Even now, as BLM protests continue, the perversion continues. People being threatened by yobs in army surplus, even outside their own homes. Faceless, heavily armoured riot police fingering their nightsticks. Bearded sex cases with huge, throbbing arsenals of hate and destruction. An obsession with the castrated, impotent rage of The Punisher...
Freud would have a field day. But then, he knew the Nazis too.
The gleeful taunting of 'blue lives matter' whataboutery, of sirens being blasted at all times, of tear gas and protestors trussed up and humiliated, barred from going to the toilet... Sadists love to play with their victims on many levels.
These people are sick, and their apologists are enabling perversion on an institutionalised level.
To understand police, then, study De Sade, Pasolini's Salo, and, for that matter, Dworkin.

While I do not believe ACAB is true, there are definitely many, many metropolitan departments which are probably almost completely or completely rotten, and among rotten cops anywhere, what you are describing might very well be common.
