Life is funny. This is turning out to be a repeat of exactly what Junior's father went through. He kept "beating" the government. But they kept coming after him, and eventually they nailed him. The only difference here is that John Sr. went around bragging and boasting of how the government could not nail him. Junior on the other hand has pretty much kept a low profile since his last couple of trials.
Both Pizzaboy and Turnbull have correctly stated :
Unless "Junior" has, in fact, secretly cooperated, the feds will NEVER be done with him. Their memories match the size of their wallets. They have nothing but time.
Not that I have any sympathy for that gavone,but Junior could join a cloistered monastary and the Feds would still be after him.
