Very good point Moe,a person might think that those kind of guys would be the first to rat.Even though they were coke heads they didn't rat.Maybe the FBI couldn't use them,who knows.
Another thing,Bruno was born 1947 and his father Sonny Red was born 1931.Could it be that Sonny had bruno when he was 16 years old,or is that just a mistake that spread over the net..?
