certain "people" are making this out to be a lot worse than it actually is.
I have no idea what you mean by certain people. The issue of police "overkill" came to my attention, when cops in my town shot a teenaged girl in a school playground. She had a knife, and they claimed she lunged.
So I am "certain people," she was white.
Later cops strangled/beat a KNOWN mentally ill man to death. Our family knew his family. I am "certain people" and he was white.
In the latter case, the county DA, a law and order Republican, pursued cases against the officers, but a jury failed to convict, much to the disappointment of a majority in the area.
