XD This is my analyzation.

Unless we have a sudden shift, it seems most likely Mia Fey is going, this is to see if Gotti is lying about being the Day Cop or not, is she comes up scum, there is only two realistic option Gotti may have had planned, he's telling the truth or he is using a powerful Mafia role to further himself, most likely the former. So to abstain from possibly wasting an inspection, we can try to use the power of reason to see which placement Gotti is in.

If Mia Fey comes up innocent, Gotti is either ignorant or lying, so there are three options I have in my head, Gotti has no idea how to play the game, he is Mafia (which is most realistic to me) and got caught in a bluff, or there is the outside possibility there is a third or neutral faction. So we should lynch him anyway, for he is either a parasite who just hurt his own faction, in which he should be lynched, scum, in which he should be lynched, or a member of a third faction, in which he could be lynched, depending on his role. So it's really easy to determine what to do with him if he lies.
