A rich celebrity who paid zero taxes only getting 2 years seems to be confirming that white collar crime is largely unpunished, not a counterexample.
If he'd paid a fine after they caught him, he wouldn't have gone to jail. He very openly refused to pay. He effectively went to jail for refusing to pay a fine.
Black guy. Different thing. I've noticed that many of the scapegoats for the flash crash, and other similar things are not white.
