"Vyshinsky: Were you badly treated? Muralov: I was deprived of my liberty. Vyshinsky: But perhaps rough methods were used against you? Muralov: No. No such rough methods were used. I must say that in Novosibirsk and here I was treated politely and no cause for resentment was given. I was treated very decently and politely."
