Might as well get this out of the way - I had already discussed this extensively in dead chat, but I expect to hear some more complaints about the Cop thing, so now that you're on the winning side - hear me out.
The cop had an actual utility for the split mafia team - it was to help you locate your lost allies. There was never any guarantee of the unification happening. While I had no delusions about how the role would be received, had there been a single scum flip over the course of the game, I think it would have introduced the possibility into reasonable role spec. As the game was a clean sweep, admittedly, it couldn't be reasonably expected that you would be flipped.
Had the cop role not existed for you, I probably would have had to introduce two scum role cops. Had this been a bog standard 5 man team, I probably would have never introduced the cop for the explicit purpose of rugpulling town - it was a role with a utility and a function, and town was compensated with Boone (Phenom) who was functionally the cop (Arguably better, in a lot of ways). Unfortunately, he bore the scrutiny over you. I think there was a few other context clues that should have led to not blindly believing your claim, but I'll leave it at that for now.
I expect a lot of complaining about the game as it played out, but from a bitd's eye standpoint, I think a lot of things also went right for scum, and a lot of things went very wrong for town, and even in spite of that town had a chance to turn things around and ultimately didn't.
