Mafia 101. Disputed Island

I completely don't understand why no one is going to hang Alex, for whom there is evidence (and a very good one at that), and the odds are against him. Moreover, Bob probably went to see him if you read the latest posts before the Shaman was hanged.

If this were a classic live game, such persistent defense of the mafia member would not have left any chance of avoiding execution.

I considered the shaman suspicious, but, I repeat, Alex seemed much more important to me then. And still does. Here.
Now there are no shamans, who, of course, were much more dangerous than Jen Li. So why not hang him today? He seems like some untouchable person.
