Look, information kills shouldn't be Town/SK's strategy (they're the same right now). Right now, we have to rely on some luck to win this game - we need the Blind Assassin to successfully kill scum tonight - and than hopefully garner enough information from the scum flip to vote out scum.
There's a decent chance that the BA used his tracking in the previous night (I mean, he still could of killed someone, but there's a good chance he just used his tracking) - which hopefully he chose the right person to guarantee scum kill somebody, or at worst case, rule out 1 person from his pool of people to NK.
