Well I mean we were under the assumption that our sheriff/Vig didn't have any sort of doc capabilities so the best plan is to lynch Kaz and have him investigate somebody.
Since he says there's no way he can die this round (according to him) he's useful for at least one more round. This isn't any different than when Dr.S has been the sheriff before and we've tried lynching him and he's been forced to come out with his role.
I'm sure we'd all like to believe you're telling the truth but there's too much risk for the town if you're lying.
