Oh I didn't think of it that way Walpiurgis, thanks for your clarification (neutral read now).
@Alistair your fakeclaim still looks very scummy imo: if you're a cop, why saying you aren't? If you're a doctor, why claiming a cop that has already used its action? If you're mafia, you could disguise as cop to make your ally look town, right?
Another question: if you're not the N2 cop, how do you know Paul is innocent?
At the moment my main suspects are Alistair and Paul, so I'll keep my vote
