In essence, George makes a good point in that the guy may have indeed structured his assets in such a way as to lawfully avoid taxes.  Remember, while it is illegal to evade taxes, it is not illegal to avoid taxes.  To get the fine line between these two terms, think of it in terms of driving a car.  You can avoid an intersection controlled by stop lights by taking a different route, but you are disallowed from evading the police who are flashing their lights in pursuit of your vehicle when you run a red light.  Same thing with taxes;  setting up trusts or nonprofit structures that avoid taxes, taking losses on taxes, etc  are all legal things.

Given innocent until proven guilty, I'll await a jury's of 12 of our peer's decision before deciding that he's a criminal.  Sounds like you've prejudged him, where others have kept their minds open to the possibility that he's a legit business person.  Interesting.
