I started this before I saw Bagel's post, but I'll post anyway
I think it's safe to clear Pasonia, since he was the first one to say he received someone else's innocence in their PM. Also,
this post I believe clears BagelBob, since he states here at the very beginning that he already knew Derekku was innocent (even though it seemed like a joke at the time).
This leaves Derekku and LadySuburu (and me I suppose)
I asked strager right after I got my PM and he said that yes, I can protect myself.
Also, I don't think we can assume that yours and Pas's results are 100% guaranteed to be correct (being Crazy Mafia and all), so we aren't sure of your sanities either. Still, I am leaning toward lynching Suburu tonight, if no one else has any objections?
