What happens if Jiro lives? He is a likely target for mafia violence and does not make it to Day 2. If he dies, we'll know that he's caused a stir enough to be singled out as a target. Mafia can take this target as an obvious choice, or not be obvious about it and pull a Kansas City Shuffle on us.

If Jiro doesn't make it to Day 2, well. That's something interesting.
