Indeed! They keep pushing, I fear one day we will wake up to a full blown civil war.
The truth is, most black people don't commit these sorts of heinous crimes. Blacks may be kicked-in-the-head, politically, as a general rule, but most are law-abiding citizens.
This sort of gangster thuggery has plagued the black community for a very long time, and in much greater depth than it has on the rest of the culture. You don't hear about the atrocities that occur in "the hood" too often, but there's a near epidemic of violence occurring there.
