The LCN also had to many rats they need to get that under control.
Its hard to do it because many mobsters doesn't had the state of mind of their fathers or grandfathers;out any myth on the mafia,before the omertà was lived as a way of life:don't speak with cops,made money in the shadow,obey to the boss ecc in the 1980s with the Rico law a mobster can find an exit and flipped saving his live or don't go in prison.
Now the LCN is more american that sicilian and only the zips and few mobster follow the old rules.
The only take the rats under control is to prefer quality to quantity.
