Actually. 78% of the black on black crime results from segregation into self made ghettos.
Thee other 22% is mostly the result of disgruntled women asserting their strength on their men
Any stat that is over 75% will do as a basis. The segregation won't be the work of anyone but the Blacks themselves. Some Georgia mayor wants the South to be a Black "haven" and I've seen a lot of Black this and Black that days/colleges/orgs, but never a White this or that.
