The RICO act was an underused tool when it first came out. It wasn't until about ten years later it was started to be used against top wiseguys. As smart and careful as Gambino was I think in another era, say the 80's, I wouldn't have been surprised if he would have got sent down. With the RICO act you've just got to be implicated with two or more mob activities and you're going down for a long time.
