Gotti's fate was sealed from the get-go. The Feds had an iron clad case with or without Gravano's testimony, and pulled out every weapon they had,to avenge the severe bruising that the egos of Law Enforcement suffered at Gotti's hands in previous encounters.. Sammy was street smart enough to know this,and to also know that he would go down with Gotti in this case. His motivation was survival, pure and simple. Better to cut a deal and basically walk,than to catch a Life sentence. His testimony was a nail in Gotti's coffin.but only one of several. All the B.S about Gotti wanting to set Sammy up to take the fall is just that..B.S. Gravano is an opportunistic thug . The guy gets 5 yrs and keeps a lot of his money,yet uses that break to get involved in crime again. This time he goes from a piece of sh*t legbreaker to a piece of sh*t drug dealer,all because he flipped on a piece of sh*t gangster.
