I've been thinking, maybe FF's question isn't so useless. It may not help now, but it may help sort out who is scum later in the game, when more connections can be drawn. Therefore, I have decided to answer it.
If I had been selected as the murderer, I would have picked JB for the simple reason that he has an uncanny ability to pick out when I'm scum.
So frame up or hoping we would dismiss as a lie?
