If a senior figure in a family wanted someone clipped (And I say senior figure because it's not a strict case of rank and file like it used to be) then they wouldn't have to ask many people, and they certainly wouldn't care about any commission. In fact the commission as has been known in relation to LCN is all but defunct. That's not to say bosses/higher ups of all the families don't meet, do business or consult, but it isn't the 70's.

And as gangstereport said, often the fear of violence is enough. If you ask 100 random people what do they think of when the hear of the Mafia then murder and violence will be mentioned a lot. A lot less people get killed these days but you are still dealing with people who will get rid of you if they deem it to be the right thing to do.

Make money, not headlines. I'm not sure who said that but it's true now as it ever was. The mob have a bit of breathing space, the feds aren't as deep up their asses as they once were due to terrorism and they would be stupid to start dropping bodies while they have it relatively good. The odd one will still fall in all likelihood, but the mob is evolving and changing and less violence is something that seems to be holding strong.
