Hmm....Thucy and The Jok3r both have good points. While I do believe it is important to have numbers, information gathering is also important. I would like to enlist the wisdom of probability and risk management. Through the first couple rounds information will be at a low, as such any votes cast by the town will be rather random. So if we cast a random vote we have a 5/18 or 27.8% chance of eliminating a mafia member/ serial killer, and if we miss the mafia is sure to kill a town member, unless they by a miracle kill the serial killer. However i would like to bring up an important fact, by randomly guessing, we have a better chance of killing an important bad guy (mafia, serial killer) than an important good guy (cop, doctor, vigilante), so why we may end up killing our doctor, we have a better chance of helping ourselves. Granted this leaves of 10/18 or 55.56% chance of killing a normal person, but us normal people are expendable. Also, the mafia know who each other are so they have a better chance of killing our goods guys than we do. And abgemacht also makes a good point, 1-3 people will be dead tomorrow, most likely two of ours, so we may as well take the first shot, even if it is in the dark, instead of just taking a disadvantage. I hope this makes sense.
