Because he was dead for sure, and if I wanted to I could probably have gotten out of the poe by voting DS earlier and sheeping you and chess. That would prob be my wincon if I was scum. Any attempt to save DS is just tieing myself to a sinking ship after he flips.
But I didn’t vote DS earlier because I legit didn’t get the rationale behind it and I wasn’t fully focused on the game given that I was on mobile.
When his 1-shot cop claim failed, and I didn’t vote him until quite a bit after that. I was thinking that having multiple cops might’ve been a thematic thing so I trusted my initial read of him until he started imploding and the DS. from small street mafia (game on smogon) started coming out.
