However, when you learn through experience that cops themselves seek to harm you, then what? There is no recourse! Who will try the cops? If you do fight back publicly, who will stop them from endlessly patrolling outside your house seeking some minor infraction? Who will stop them from burying you in fines? Your elected representatives are your only option and good luck with that. I'll assert that in human psychology this helplessness reasonably magnifies fear beyond the statistics.
In fact, when you come through experience to fear the cops it also makes the _criminals_ more terrifying -- calling the cops becomes like running to the lions because you are being chased by wolves. So you just give up and let the wolves consume you.
And pure conjecture here maybe criminals know that, which emboldens them to preferentially predate upon black people thereby producing your original murder statistic.
