No i dont think hes active now, to my understanding it worked something like this, they would set up these "dummy corporations" that only existed on paper and they would buy and sell large quantities of gasoline and instead of paying the mandatory federal taxes on the transactions they would pocket it as profit and when the government came to collect the back taxes the company would evaporate and they would just create a new one. The govt said that if they werent so greedy they probly couldve continued doing it for another 10 or 15 years without getting caught.
