As usual, the culprit becomes victimized. They will argue that transphobia was the reason.If they had evidence she was molested or something and thus they could spin it as "oppressed trans faggot takes vengeance on evil fundamentalist rapists"(implicitly) they would have done so I think. Its probably just a way for libtards to justify what happened beyond "they were White/Christian and thus it was good because ideological war" as some of their peers have.
I imagine if we ever see a manifesto its either going to be heavily edited and doctored by the Feds, or we'll never see it at all.
