I've said multiple times that I think it's almost too convenient that everything lines up for if e is lying scum. I think that's the answer, and since that will no longer put him at X-1, I will
Vote: e
Wait, it's too convenient that e is lying scum, therefore he's lying scum?
I mean it's too convenient that there's not a single angle that incriminates him. It's like it was fully worked out at night that this move had no chance of failing. It's a perfectly timed power play to get to triple (but really double) lylo.
What would be the angles which would incriminate him if he was Town? Such a play clearly does have chances of failing; we could exile e. What if iguana was a PR? What if another Cop had an innocent result on iguana? Why would scum out one of their own for a likely double lylo when they could have gone for an actual triple lylo?
If e is town, there's nothing to incriminate him of course. But still, why not use the 1-shot N1? Even if to get effectively an IC... masons weren't known at that time. And getting a result N2 of scum, especially as a 1-shot, is a pretty obvious town move to claim in your opening post. He strung it along to see which way it would go, before settling on the claim of 1-shot. Those are not town plays.
And yes, you're right, things could have gone wrong. Maybe we were close to one of his partners, and he's a more disposable goon, so it was determined to be worth it.
We may exile e today. I think we should. But if a cop claims a scum result, isn't the obvious move to kill the "found scum" first? Then if that's wrong, we exile the false claiming cop. If that's the assumed route, putting his team to double lylo is a move worth making.
Another cop having innocent on iguana was likely the biggest danger. But which cop would investigate him? It makes more sense to figure out why someone avoided an exile... me, joth, even you Jimmmmm. Those make sense as an investigation. Iguana made sense as a fairly safe claimed investigation. Just interesting enough to have a reason to claim it, but not interesting enough that a real cop would investigate him.
