I don't think it would be prudent for the doctor or detective to reveal their identity, even if they were still alive. They would clearly be the next lined up for a hit. We don't even have a way of telling if we got any mafia at all yet!

I think that's what I was trying to convey before, but it seemed like bloodthirst, and I suppose that may have cast a suspicious light over my own person.
I'm not advocating belligerence, but firmness in our beliefs as a town.
