It´s been awhile since I read it. I can´t remember that book having a lot of factual errors though. There are other Gotti books from that era (early/mid 1990s) that are far more unbearable than Howard Blum´s. (Wolkman´s for example.) This one is pretty well researched and if I remember correctly, you can find a lot of wire transcripts in it.

Nice to see you posting on a regular basis again, Yigido. I remember when I first joined this place, you were the first one to welcome me aboard.
