Night scenarios
The Sheriff found two civilians
These are two points of trust, but not proof about the others. The decision to reveal depends on risk.
The Sheriff found different gangs
Strong information for a reveal, but both gangs may argue and counter-attack.
After the first night the Sheriff has two results of different colours. If they reveal themselves, they can show the conflict of three sides and suggest voting against one checked mafioso. But rivals may deny their role; the city must compare the history of the statements and the consequences of the choice.
The Don found the Sheriff
He can choose a target, but the hidden queue does not guarantee that the shot counts.
Both gangs shoot one player
The victim dies; the others do not learn whether the targets matched.
When the target matches, the player dies for certain. This is one death, not two. The city does not get reliable knowledge of which gang picked the victim and should not automatically reconstruct the queue.
The Sheriff died before revealing
The results do not pass to the city automatically; the roles of the dead are hidden.
The results they collected do not automatically become public. The city has to rebuild the versions from speeches and votes. At the same time the fact that the Sheriff died is hidden while roles stay unrevealed.
