FBI Agent can only get results on serial killer, he won't find regular mafia, or werewolves in this case. You could say you're a cop, but there's definitely a cop role in this game, and I don't want us two linking us together. If one of us go down, then the other is shortly following.

and yes, if it turns out we're the only pro-mafia faction after tonight then I won't step out as FBI Agent. I won't do it until I know I'm in trouble, which is what an FBI agent would do.

I'm pretty sure there's two mafia groups and no serial killer, which is why it's nice to make it sound like there is one.
