Why Doesn't Anyone Notice.... (spoiler)

That Gino and Jerry have something very much in common. They both know too much and their lives are completely expendable.

The Mob always intended to kill Gino. They never had any intention of fulfilling their side of the deal. And Jerry, a member of his crew so on the outs that he was relegated to "women's work", was given such an important assignment precisely because they intended to kill him after he killed Gino.
