Want to be a criminal and get away with it? Become a lawyer....
That would make things a hell of a lot easier, but lawyers sometimes get life sentences for organized crime related crimes too, even successful ones. Random examples: Paul Bergrin in the USA and Raffaele Bevilacqua in Sicily (he was a Commission member for the Enna province if I remember well). But it's difficult to send away a lawyer, that's true. Better than that, only immunity that national-level politicians have.
