Okay, I'm having trouble following your Lynch to prove Sanity Logic.

If you investigate yourself to prove it, you can at least get a good Idea on your sanity. (Innocent can be either regular or Naive) but on someone else you can't even be sure until they flip. So if you doubt your sanity, how does investigating Dynast help you out unless he flips?

I mean he didn't seem like he would be a target for the Mafia, (Though turns out I was wrong in that thought) and he was the likely one to get lynched today, so an investigation on him wouldn't have done anything to prove your sanity until he was lynched. Given how there was a chance he would get off, it seems more practical to do a self investigation then investigating him.
