I'm not pointing fingers at anybody, I just find out of the remaining players, that TRS is an odd choice to go for so quickly when it's just as likely it's one of you crafty, experienced types.
It's hard to say that TRS "knew" things when it happened that his impulses lucked out and he happened to be right a few times. I just find it less likely that unless he's being coached he would point out innocents and then hit them or something.
Can you see or find anything from the experienced players that lead you to believe they are mafia? If you can quote instances for us all to look at it is helpful. You may see something that we have not seen.....anything that pops out as suspicious to you?
