Part of what seems to have gone wrong in Charlottesville – though, as Jim Wright says, you usually don't have reliable data until a week after the events – is that the local police went easy on the fascists, allowing lesser – though still potentially lethal – acts of violence. Another part is that Donald Trump and some of his administration (Bannon, Gorka, Sessions) are supporters of the fascists. The fascists, with some reason, believe they are likely to get away with acts of violence. President Trump has yet to condemn the white supremacist ideology of various alt-right factions involved.
We are now looking at, I think, the worst act of far-right domestic terrorism since the Oklahoma City bombing. I fear a crackdown, which, given this administration's direction, is more likely to fall on the opposition to the fascists than the fascists.
