I have got at least one wrong result in my investigations. So it maybe that I am a Naive Cop So all my investigations will turn up as crooks. This is entirely possible because of the way the game is structured. I am the Crime Lord and I assembled the team. So of course I assembled only "crooks". I am not going to knowingly recruit someone who maybe a cop. So when I "rack my brains" about someone I can find nothing incriminating against them. So in this scenario, you are the actual cop and I am just a decoy.
Also I am got the results "crooks" in green from the mod. I had not mentioned this part earlier. The fact that robert also gets the same thing is confirmation that he is indeed town. In terms of me being town -> There is no mention of a Crime Lord being in the game anywhere. You are the Crime Lords son. So I couldnt have guessed there is a Crime Lord and claimed it. So that is proof that my role claim is not false. Unless you want to say that the Crime Lord himself is an undercover cop
I also believe kevinH's claim. So this just confirms the Perfect Mafia and iSocialism are scum.
As for robert's "no results", I would guess that one of the scum is a role blocker and they blocked you on N1 and N2. I am not sure why they didnt roleblock or even kill in the night though. Maybe they were inactive?
