People are angry. They want people to be held accountable. We're in a place where spells have a tendency to backfire for a variety of reasons — whatever it keeping us here in this dimension, the radiation, hell, maybe just the oxygen being that much off from ours back home — we don't know. No one does.
Next time, it could be anyone else with a backfired spell, and that's what worries me. I don't think Swan did a spell to send people to Storybrooke. I think she did a spell that had those unwanted, traumatic consequences for whatever reasons.
Satan literally brought a coffee shop here, and people were lining up for coffee, not wondering about the consequences of that magic — which, FYI, I'm still waiting for. Mark my words, he's going to use that for something.
