Intention? What are you talking about? Neo-Communists like this have attacked attendees to conservative speaker events at Berkeley and elsewhere, and rioted to shut them down. Civil authorities have looked on and taken little or no action.
So they have dished out violence, it goes well beyond intention, and it is long past time for a group like AntiFa to be dealt with as a criminal enterprise under RICO.
I should have been more clear; there will be outright murder (as has been seen directed towards policemen). They should be dealt with as insurrectionists, not just “criminals”.
