"Usually good" isnt good enough, being a public servant you need to be good 100% of the time when it comes to the lives of other people. Even if accident, that shows lack of poor judgement and poor judgment should equal find another job (of couse Id want the slammer if found with intent.) The entire department should be held responsible and relieved of their public duties at this point including the courts they work in.
I think the big factor, and this is just my opinion is that the most important color is green. I notice most of these problems arent necessarily "black" communities (whatever that means?) but rampant poor communities where poverty leads to higher crime rates, higher crime rates lead to higher police activity, and lack of green also equates to the inability to acquire quality legal protections and to afford bail so many other people here benefit from while in due process. Alot of poor people end up behind bars while awaiting full trial and sometimes this takes well over a year, there is no "corrections" being done here in this process for small time criminals and those who arent guilty of anything.
If this is a topic of interest for you, you should look into Robert Moses
https://en.wikipedia.org/wiki/Robert_Moses , he is a freaking engineering genius and is responsible for so many incredible infrastructure projects here in NYC (I live north of that, was just there in Manhattan yesterday picking up the new iPhone, the city is always incredible.)
There is a series included on Amazon Prime called "American Experience: New York" by Ric Burns (2003.) I think it was episode 6 "City of Tomorow) that showed how Robert Moses created the projects to throw non-whites in and he went to extremes to specifically build street bridges that were so low city buses couldn't pass through so the minorities were stuck in these areas with limited access to get back into the city for jobs and stuff. Its really sick.
Anyways, what Robert Moses and his version of NYC did end being the role model city to push minorities out from mainstream populations that many other cities around had followed. Im sure this has still effects to this day as I know first hand welfare/poor societies have the potential to be generational.
Anyways back to my point, the color of importance is green and only green.
