Cop
Townie
Each day, the Cop PMs the game leader whom they wish to investigate. The result will either be innocent or guilty. Exception: the Godfather is always innocent. The cop can choose to make his discovery public in order to sway the lynch vote, or may keep it secret until he/she has more information. Naturally, once the cop reveals himself, he will be a target for the Mafia. Perhaps the Doctor can protect him. But what if a Mobster is pretending to be the cop? Then if the Doctor protects him, he is protecting the wrong person. The Cop may also choose to be more sly about revealing his information by coyly laying out hints when he posts about whom the Town should lynch.
In some games, the game leader chooses to reveal the name of one of the mobsters to the cop before the first lynch vote.
