Heather Mac Donald is one of the few journalists who gathers good, clear facts in many crime cases. She has an excellent article at City Journal on the stats for black-on-white crime and their relationship to the Chicago torture video:

Anti-police activists and the mainstream media are incensed at the suggestion that the Black Lives Matter movement could have influenced the behavior of the four individuals in Chicago who tortured a disabled white man for hours last week while yelling “Fuck white people” and “Fuck Donald Trump.” In one sense, the activists and media are right: The influences were broader than that. They include the reign of racial victimology, inner-city gang culture, and black anti-white animus.

We live in Ta-Nehesi Coates’s America, characterized by the assumption that blacks are the eternal targets of lethal white oppression. Coates’s central thesis in Between the World and Me, his acclaimed phantasmagoria of racial victimology, is that America continuously aspires to the “shackling” and “destruction” of “black bodies….”

Radley Balko rushed to tweet out that the Chicago kidnapping is not a trend because since 2001, 80–85 percent of white murder victims were killed by whites. True, but the percentage of blacks killed by blacks is higher. From 1980 to 2008, 93 percent of black victims were killed by blacks. White-on-black homicides are much rarer than black-on-white homicides. The vast bulk of interracial violence is committed by blacks. In 2012, blacks committed 560,600 acts of violence against whites, and whites committed 99,403 acts of violence against blacks, according to data from the National Crime Victimization Survey provided to the author:…

Blacks, in other words, committed 85% of the interracial crimes between blacks and whites, even though they are 13 percent of the population. This data accords with the last published report on interracial crime from the Bureau of Justice Statistics; the Bureau stopped publishing its table on interracial crime after 2008, the first year of the Obama presidency.

The violence in the Chicago torture video does not arise in a vacuum. Most residents of inner-city areas are hardworking bourgeois citizens longing to live in safety and in racial harmony. But the video opens a window into a culture that America would prefer to turn its eyes away from—and which it has helped create.
