Did you openly scum or town read this person? If you openly town read them, then I'd think the vote was misdirection. If you openly scum read them, then I would more likely consider it a defensive action.
If it's misdirection, what was the intent? That you would scum read them? That town discussion would be diverted from elsewhere? There are a lot of possibilities.
There's also no guarantee that this is a scum power. Could be part of a neutral win-con.
If me looking for an arsonist was scummy yesterday, what's this then?
