Yeh I've read Sammy's book endless times over the last two decades & when Phil mentioned Sammy in his book, he just repeated the same stuff Sammy wrote about but made it appear like some inside info which it wasn't

The only new thing he offered was that when he saw Sammy in protective custody after they flipped, when they would walk the yard.. Phil claims he himself was done with the life but Sammy had other plans and was even trying to get him to join him once they got out
