Well, there's no excuse for not paying taxes so he has to be punished (and pay the back taxes). However, I don't think he'll get 3 yrs. Our jails are already too crowded. The legal system should be finding alternative punishments for non-violent crimes.
Wealthy people like Snipes pay a ridiculous % in taxes, I don't blame him for not wanting to pay, he deserves more of his own $. Thats why we have to change our gov so its easier to cut spending than raise taxes.
