Did it ever dawn on Roy that most people in the black community never so much as heard of neither the victims nor the criminals before the crime was committed? The same as you or fellow white citizens would have never known, let alone heard of Dylan Roof, Adam Lanza, Wade Michael Page, Jared Loughner, or Tim McVeigh until they committed their crimes? You'd have just as likely set in church next to some of them, greeted them on the street in passing, and considered them good upstanding citizens, raised right by their parents.
The black community can't tell the police what they possibly don't know, no more than you could predict or should be blame for the actions of the above mentioned whites who committed crimes. It's not like slavery, where slaves were forced to name someone, anyone, even innocents, or risk being tied to the whipping post or worst. Thank goodness those plantation days are gone. Over! Done with! Zilch!
Now think in the terms of "we're all free now." Free at last! Free at last! Not all black people know "all" black people.
Get off the backs of the black community. No matter what your police buddies tell you, you have no idea the driving force behind much of what's been taking place or why in primarily poor and black communities for the three to four 4 decades.
In the words of Frederick Douglas, "Just leave us alone!"
