Frieza cleared his throat loudly. The discussion was getting off track.
"As I said, I advocate we cast a collective, public vote on who should be investigated the first night. As much as I, too, would prefer to take complete charge, our greatest weapon against the mafia is the weapon of collective knowledge. The mafia knows who the other mafia are, but we don't know who the other townspeople are. Rather than point fingers at whoever seems the most suspicious, we should snuff out the mafia through process of elimination. Ideally, the investigator will choose a townsperson the first night. If the investigator does not come forward, we will assume that person is aligned with the town, and add them to the count of confirmed townspeople. That way, when the investigator does find mafia, they can relay that information through one of the confirmed townspeople so as not to make themselves a target.
"By the way, if the investigator does find mafia the first night, they may still keep quiet. While strictly speaking it will be erroneous to assume that whoever is investigated the first night is innocent, it is still a fair collective assumption to make. Should this happen, the investigator will simply investigate the next person we pick, until they reach a townsperson--at which point the information they have gathered regarding who the mafia is will be relayed through that person. And we'll know if that person is a liar rather quickly, by way of coroner report. That way we gain as much information as possible without putting the investigator themselves in any danger whatsoever."
Hopefully the people here weren't too dense to understand this.
"The question is," he continued, "do we vote for the most suspicious person to be investigated, or the least suspicious? Higher risk for more information gained, versus lower risk for less information gained.
"Also, I advocate that on this first night, the doctor should protect themselves--if possible. Their role will only be useful should somebody with a valuable role be forced to reveal themselves later, and they should do everything possible to survive until then."
