Again, I haven't posted because I've been asleep. Damn time zones mean everything happens here during the night.
For the record, I support the sanity test on the cop. Cops can target themselves (I think), so if they return the opposite of what they are then they know they're insane. That way the cop doesn't need to be sure Khuutra is Town before agreeing to the plan. It's wasting a night's investigation but you can probably trust future ones.
With this wave of roleclaiming, I'm not going to do so.
