The confusing thing is that there are people in this town called the mafia who are going to use everything in their power to make themselves look innocent and other people look guilty. We (The townspeople) have to decide for ourselves which arguments are from a townie and which are laced with mafia poison. There is no way to be 100% sure short of their role revelation upon their death. It's actually funny how this very confusion is part of what makes this game fun though.
Also can you please clarify the last sentence please? Right now I read it as you are saying that you won't be lynched and I'll die tonight, and thats a distressing thought.
