If Marcello "flipped" I believe it would be safe to say we would have a Family Secrets 2, maybe 3 or 4 ! Yeah, he for sure could answer some questions.

I believe I read an earlier post where someone said he would never flip; too hardcore and just plain tough. Old school. I guess anything is possible especially if you're facing spending the rest of your life in prison. Everything I've read about him indicates he is a very, very tough hombre.
