One of the best ways for a mobster to stay under the radar is not to get formally "made." As soon as he is made, his new "brothers" will rat him out to the nearest law enforcement guys in order to curry favor. He'll get more law enforcement coverage than a visiting head of state.

Of course the Catch-22 is that the guy does have to get made in order to make real money and move up. The smart thing is to become a bigshot corporate executive--then you're merely a "white collar" criminal.
