Wouldn't they see it more as buying Cid time? It would make sense if Cid was the last mafia member and Hsu was the bomb, mafia wouldn't want Hsu to be the last one standing. If we do that and all works out we would 1) get rid of the cop. 2) get rid of someone at night. 3) get rid of Cid the next day, and 4) get rid of someone else at night. Then they would lynch Hsu but that's 4 more citizens down XD

Only I am kinda reluctant to sacrifice Hsu since he's not suspected by anyone (except eestlinc, and I don't think he was very solid on it) right now.
