No, even if he was a starlett, they wouldn't have let him out in a week. Driving drunk, and therefore showing callous disregard for the lives of other drivers on the road is no big deal. Heck, killing an innocent person while driving drunk won't get you much jail time. Yes, this is verbal irony, and I find these things outrageous.
But man, if you evade taxes, well, you're hitting Uncle Sam in the wallet and it's all over.
The got Capone on tax evasion.
The back story is that Snipes bought into one of the groups that peddles the "you don't have to pay taxes because..." line. Well, court case after court case says despite all the objections, you really do have to pay taxes, and the government will catch up with you if you don't.
They caught up with him. You can argue all you like about how invalid the 16th amendment is and why, but when it comes down to it, they're going to put you in jail for evading taxes, period. So don't bother with the technical arguments. If you don't like a law, lobby to change it, don't break it.
Mr. Snipes chose poorly, I'm afraid, and he's probably going to do time because of it.
