Absolutely. Note Boobie´s voice which sounds "soft" in some way. And Pistone´s voice seems to change into a brownnoser´s when speaking to Sonny Black.

I think Tony Mirra was caught on wiretap. But I don´t know if the audio book has anything on him. Sonny Black (the poster in here), (or anybody else who have downloaded the book) might be able to tell you.
