All "Flashmobs", and Gang-activities where they do things like a pack of hyenas together are black, the lone and calculated serialkillers that have prepared things beforehand are white.
not just whites, but whites of northern european ancestry ie. German, English, or Scandos
not many jews, italians, spanish, greek, or french doing this cold-blooded serial killer stuff, basically coz they ain't cold and ruthless enough
bundy, dalmer, panzaram, gacy, etc all can trace thier ancesteral roots to northern europe
