There’s no such thing as “black-on-black” crime. Yes, from 1976 to 2005, 94 percent of black victims were killed by black offenders, but that racial exclusivity was also true for white victims of violent crime—86 percent were killed by white offenders. Indeed, for the large majority of crimes, you’ll find that victims and offenders share a racial identity, or have some prior relationship to each other.
