The LCN sometimes does hits in a way to send a message to others. For example:

-Members of Vincent Gigante's crew brutally tortured Anthony "Tony Bananas" Caponigro before beating him to death. They then stuffed $300 in his rear to show that he had become too greedy by killing his boss (Angelo Bruno).
-Sonny Black Napolitano's hands were chopped off because he shook hands with Donnie Brasco, who in actuality was Joe Pistone, an undercover FBI agent (albeit unknowingly). Napolitano introduced him as a "friend of ours" when Brasco was not a made guy.

Are there any other prominent cases of using metaphors in murders committed by the LCN?
