I think the disconnect here is that you're talking about an ideal world -- an ideal world I agree with and want to make happen -- but most other people in this thread are talking about a world where capitalism is falling apart at the seams and we've already had months of street violence.

If we're talking about an actual revolution having a prayer of happening, yes, sometimes killing a reactionary without trial or formal authority will need to happen. If we can't stomach that, holy fucking shit we're going to get lined up against a wall and shot.
