Мафия 13. Inanimate Paradise

I'm reading all this and getting more and more confused. About the evidence in Necropolis, about everything in general. I don't know if it's due to inattention or inexperience. For now, I don't see any evidence that would justify executing anyone. (The only 100% evidence was against Brekman: the hammer, the curved weapon, clearly a sickle and hammer - communism, we've already talked about this, and I think no one doubts anymore that he was a hellish spawn). But there's no other choice. It's the 4th day, and no one has been executed yet. I didn't quite understand why they want to execute Nairu, Hermit, and Taco? Guys, please explain.
