This is a study from last century. mbig seems to have an agenda, but I don't think that ethnic cleansing is part of it. What about, hypothetically, if the current violent crime rate in Chicago from black neighborhoods was reduced to that of the white neighborhoods? What would this "all-white" version of Chicago look like for a rate of violence?
True. The FBI has data for all of those, too.

Of arrestees for whom ethnicity was reported, 18.4 percent were Hispanic.
Of all juveniles (persons under the age of 18) arrested in 2015, 62.9 percent were White, 33.9 percent were Black or African American, and 3.1 percent were of other races.

White individuals were arrested more often for violent crimes than individuals of any other race and accounted for 60.1 percent of those arrests.
