Here's a question/observation.
Supposedly a mob person should get permission before killing anyone , but especially before killing another made member or someone completely uninvolved in the life. But is this "rule" even adhered to any more? Roy DeMeo murdered a made man when he was still an associate. DeMeo would go on to kill many other people-some of whom weren't criminals-with only mild expressions of disappointment from Castellano. Tommy Pitera and Greg Scarpa killed numerous people without any permission slips from higher ups. If we go back years before, Nicky Scarfo killed a longshoreman in a fight and was only exiled to Atlantic City.

How true is this rule, if it ever was?
These days as a Mob captain or underboss with the feds everywhere, why would you want to take the chance of being caught giving explicit permission to murder someone anyways?

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
