めんどくさい
I found Al Sips suspicious from Day 2 or so, and he made a comment on Day 1 about ring control measures so he could have something to do with the ring or he could be a wolf trying to minimize its impact. Plus he's guaranteed to be LOTR while Arakhor isn't guaranteed to be a wolf.
I'd be fine with an Arakhor lynch though; passive ability blocker is about the scummiest claim I can think of.
And now that LOTR Mafia are dead, whats your case against Al Sips now?
