I do not know if all of this is true. I believe it is just for the simple fact that it's too brutal and too honest. Amazing and chilling insight into a criminal mind and all that goes with a criminal life. I had always been life so many intrigued by the world of the mafia and I do believe it's because Hollywood has glamorized and romanticized it. This book brought it down to earth and showed you the brutal truth about what a cold blooded violent institution the mafia and the people in it really are. This was the first book or movie or anything I'd ever been exposed to that basically humanized the mafia for what it really was and then basically dismissed it as the subject of this book grew past it. The insight into the mind and world of a violent murderer and how he became to be what he became was both fascinating and terrifying. I could not stop listening. I finished it and immediately began it over again.
