Caboose had literally no evidence that I was the sniper at all. I was barely even participating in the game. I put forward enough participation to get the detective's attention so that I would be investigated (there's multiple factors behind this but one of them was that I put on a hell of a show last game and made everyone change their minds multiple times regarding my status as mafia).
Caboose tipped the detective's hand by messaging me. I know he is in contact with the detective because he was the first to die, and the detective is always in desperate need of a ghost. I don't know if the detective told Caboose to message me, or if Caboose took the liberty of doing it without talking to the detective first, but either way it proves to me that I was investigated.
Anyways, I don't plan on helping protown or the mafia. I'm pretty much following my normal pattern (i.e. moderators first, staff next, then randoms). My first target was actually going to be TSC, but the mafia killed him first. So now my target gets to be Bnus. After Bnus, I'm basically just going to start popping skulls at random.
So protown can't really afford to waste a lynch on little ol' me who only gets to kill people every three rounds, and the mafia can't afford to let a protown live during a night scene and let protown keep a majority of the vote on the off chance I may kill one of them, and I can manage to do what all neutrals should strive to do. Survive to the end of the game.
