I'm a bit suspicious of KoShiatar's roleclaim because
A) She had no reason to reveal herself to us because she hasn't got any results.
B) Voted for foa just to make herself not look suspicious...and this is foa who I believe to be a mafia target.
C) Investigating Leeza. Why are you doing that, KoShiatar?

If you, the reader, are the real cop and know KoShi's claims are bogus, please for the love of god come forward and tell us. If you don't, I'll believe her (and presumably so will the rest of the town) and then you've just caused the town to take a real beating.

If you are the cop, KoShiatar, then you'll understand why it's in the town's best interests to at least question you and your motives before following you.
