The point as I see it and the study IMO proves is that it ain't there. I wonder why.
The data are there for most everything else.. at least until Obama became president and DoJ became Department of Just Us. It seems that the long standing DoJ NCVS interracial crime Table 42 and other stats have gone missing.
The FBI I believe still has interracial homicide data showing black on white homicides are more than double white on black.
