If you look up "Wray under oath" videos, there's the definitions.

1. Violence happened to a person of African decent is assumed to lead directly to "Victim of White Supremacy".
2. Violence happens to anyone semitic is also assumed to be because of White Supremacy. Yes, this does mean that two rabbis and two joggers having a throwdown is "Four victims of White Supremacy" And, in case you're curious, NYC has gangs meeting the criteria for any fight to be entirely White Supremacy ... and there's no Skinheads involved. It isn't all spelled out in one clear definition, it's laid out as an inevitable path of escalation, and it's precisely why the press is so comfortable being so blatant. The FBI definitions back them up.
